# rpm-ostree CLI Deep Analysis
## Overview
This document provides a comprehensive analysis of the rpm-ostree CLI structure based on deep examination of the source code in `.notes/inspiration/rpm-ostree-main/`. The analysis covers command structure, client/daemon execution model, option parsing, subcommand handling, and implementation patterns.
## CLI Architecture
### Main Entry Point
The CLI is implemented in `src/app/libmain.cxx` with the following key components:
#### Command Registration
```cpp
static RpmOstreeCommand commands[] = {
{ "compose", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD | RPM_OSTREE_BUILTIN_FLAG_REQUIRES_ROOT,
"Commands to compose a tree", rpmostree_builtin_compose },
{ "apply-live", (RpmOstreeBuiltinFlags)0,
"Apply pending deployment changes to booted deployment", rpmostree_builtin_apply_live },
// ... more commands
{ NULL }
};
```
#### Command Structure
Each command has:
- **name**: Command identifier
- **flags**: Builtin flags (LOCAL_CMD, REQUIRES_ROOT, etc.)
- **description**: Help text
- **function**: Implementation function pointer
### Builtin Flags (Complete)
```cpp
enum RpmOstreeBuiltinFlags {
RPM_OSTREE_BUILTIN_FLAG_NONE = 0,
RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD = 1 << 0, // Run locally, not via daemon
RPM_OSTREE_BUILTIN_FLAG_REQUIRES_ROOT = 1 << 1, // Requires root privileges
RPM_OSTREE_BUILTIN_FLAG_HIDDEN = 1 << 2, // Hidden from help
RPM_OSTREE_BUILTIN_FLAG_SUPPORTS_PKG_INSTALLS = 1 << 3, // Supports package operations
RPM_OSTREE_BUILTIN_FLAG_CONTAINER_CAPABLE = 1 << 4, // Works in containers
};
```
## Client vs Daemon Execution Model
### Key Decision Logic
```cpp
const RpmOstreeBuiltinFlags flags = invocation ? invocation->command->flags : RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD;

## Daemon Communication Architecture
### D-Bus Interface
```cpp
#define BUS_NAME "org.projectatomic.rpmostree1"
```
### Client Library Functions
```cpp
// Core connection functions
gboolean rpmostree_load_sysroot(const char *sysroot, GCancellable *cancellable,
RPMOSTreeSysroot **out_sysroot_proxy, GError **error);
gboolean rpmostree_load_os_proxy(RPMOSTreeSysroot *sysroot_proxy, gchar *opt_osname,
GCancellable *cancellable, RPMOSTreeOS **out_os_proxy,
GError **error);
// Transaction management
gboolean rpmostree_transaction_client_run(RpmOstreeCommandInvocation *invocation,
RPMOSTreeSysroot *sysroot_proxy, RPMOSTreeOS *os_proxy,
GVariant *options, gboolean exit_unchanged_77,
const char *transaction_address,
GVariant *previous_deployment, GCancellable *cancellable,
GError **error);
// Package operations
gboolean rpmostree_update_deployment(RPMOSTreeOS *os_proxy, const char *set_refspec,
const char *set_revision, const char *const *install_pkgs,
const char *const *install_fileoverride_pkgs,
const char *const *uninstall_pkgs, ...);
```
### Daemon Connection Pattern
```cpp
// 1. Load sysroot proxy
g_autoptr(RPMOSTreeSysroot) sysroot_proxy = NULL;
if (!rpmostree_load_sysroot(opt_sysroot, cancellable, &sysroot_proxy, error))
return FALSE;
// 2. Load OS proxy
g_autoptr(RPMOSTreeOS) os_proxy = NULL;
if (!rpmostree_load_os_proxy(sysroot_proxy, opt_osname, cancellable, &os_proxy, error))
return FALSE;
// 3. Execute operation via D-Bus
if (!rpmostree_os_call_method_sync(os_proxy, ...))
return FALSE;
```
## Option Parsing Architecture
### Global Options
```cpp
static GOptionEntry global_entries[] = {
{ "version", 0, 0, G_OPTION_ARG_NONE, &opt_version,
"Print version information and exit", NULL },
{ "quiet", 'q', 0, G_OPTION_ARG_NONE, &opt_quiet,
"Avoid printing most informational messages", NULL },
{ NULL }
};
```
### Daemon Options (only for daemon-based commands)
```cpp
static GOptionEntry daemon_entries[] = {
{ "sysroot", 0, 0, G_OPTION_ARG_STRING, &opt_sysroot,
"Use system root SYSROOT (default: /)", "SYSROOT" },
{ "peer", 0, 0, G_OPTION_ARG_NONE, &opt_force_peer,
"Force a peer-to-peer connection instead of using the system message bus", NULL },
{ NULL }
};
```
### Package Options (only for SUPPORTS_PKG_INSTALLS commands)
```cpp
static GOptionEntry pkg_entries[] = {
{ "install", 0, 0, G_OPTION_ARG_STRING_ARRAY, &opt_install,
"Overlay additional package", "PKG" },
{ "uninstall", 0, 0, G_OPTION_ARG_STRING_ARRAY, &opt_uninstall,
"Remove overlayed additional package", "PKG" },
{ NULL }
};
```
## Subcommand Handling
### Pattern
```cpp
static RpmOstreeCommand subcommands[] = {
{ "subcommand1", flags, "description", function },
{ "subcommand2", flags, "description", function },
{ NULL, (RpmOstreeBuiltinFlags)0, NULL, NULL }
};
gboolean
rpmostree_builtin_command(int argc, char **argv, RpmOstreeCommandInvocation *invocation,
GCancellable *cancellable, GError **error)
{
return rpmostree_handle_subcommand(argc, argv, subcommands, invocation, cancellable, error);
}
```
### Compose Subcommands Example
```cpp
static RpmOstreeCommand compose_subcommands[] = {
{ "tree", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD,
"Process a \"treefile\"; install packages and commit the result to an OSTree repository",
rpmostree_compose_builtin_tree },
{ "install", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD | RPM_OSTREE_BUILTIN_FLAG_REQUIRES_ROOT,
"Install packages into a target path", rpmostree_compose_builtin_install },
{ "postprocess", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD | RPM_OSTREE_BUILTIN_FLAG_REQUIRES_ROOT,
"Perform final postprocessing on an installation root", rpmostree_compose_builtin_postprocess },
{ "commit", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD | RPM_OSTREE_BUILTIN_FLAG_REQUIRES_ROOT,
"Commit a target path to an OSTree repository", rpmostree_compose_builtin_commit },
{ "extensions", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD,
"Download RPM packages guaranteed to depsolve with a base OSTree",
rpmostree_compose_builtin_extensions },
{ "container-encapsulate", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD,
"Generate a reproducible \"chunked\" container image from an OSTree commit",
rpmostree_compose_builtin_container_encapsulate },
{ "image", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD,
"Generate a reproducible \"chunked\" container image from a treefile",
rpmostree_compose_builtin_image },
{ "rootfs", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD,
"Generate a root filesystem tree from a treefile", rpmostree_compose_builtin_rootfs },
{ "build-chunked-oci", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD,
"Generate a \"chunked\" OCI archive from an input rootfs",
rpmostree_compose_builtin_build_chunked_oci },
{ NULL, (RpmOstreeBuiltinFlags)0, NULL, NULL }
};
```
### DB Subcommands Example
```cpp
static RpmOstreeCommand rpm_subcommands[] = {
{ "diff", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD,
"Show package changes between two commits", rpmostree_db_builtin_diff },
{ "list", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD,
"List packages within commits", rpmostree_db_builtin_list },
{ "version", RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD,
"Show rpmdb version of packages within the commits", rpmostree_db_builtin_version },
{ NULL, (RpmOstreeBuiltinFlags)0, NULL, NULL }
};
```
## Command Implementation Patterns
### 1. Option Context Setup
```cpp
GOptionContext *context = g_option_context_new("COMMAND");
g_option_context_add_main_entries(context, option_entries, NULL);
```
### 2. Option Parsing with Daemon Detection
```cpp
if (!rpmostree_option_context_parse(context, option_entries, &argc, &argv, invocation,
cancellable, NULL, NULL, &sysroot_proxy, error))
return FALSE;
```
### 3. Argument Validation
```cpp
if (argc < 2) {
rpmostree_usage_error(context, "At least one PACKAGE must be specified", error);
return FALSE;
}
```
### 4. Daemon Communication (for daemon-based commands)
```cpp
g_autoptr(RPMOSTreeSysroot) sysroot_proxy = NULL;
if (!rpmostree_load_sysroot(opt_sysroot, cancellable, &sysroot_proxy, error))
return FALSE;
g_autoptr(RPMOSTreeOS) os_proxy = NULL;
if (!rpmostree_load_os_proxy(sysroot_proxy, opt_osname, cancellable, &os_proxy, error))
return FALSE;
```
### 5. Local Execution (for LOCAL_CMD commands)
```cpp
// Direct local execution without daemon communication
// Example: compose commands, db commands, override commands
```
### 6. Error Handling
```cpp
if (!some_operation(cancellable, error))
return FALSE;
```
## Rust Integration
### Rust Command Dispatch
```cpp
static gboolean
dispatch_usroverlay(int argc, char **argv, RpmOstreeCommandInvocation *invocation,
GCancellable *cancellable, GError **error)
{
rust::Vec<rust::String> rustargv;
for (int i = 0; i < argc; i++)
rustargv.push_back(std::string(argv[i]));
CXX_TRY(rpmostreecxx::usroverlay_entrypoint(rustargv), error);
return TRUE;
}
```
### Rust Compose Commands
```cpp
gboolean
rpmostree_compose_builtin_image(int argc, char **argv, RpmOstreeCommandInvocation *invocation,
GCancellable *cancellable, GError **error)
{
rust::Vec<rust::String> rustargv;
g_assert_cmpint(argc, >, 0);
rustargv.push_back(std::string(argv[0]));
rustargv.push_back(std::string("baseimage"));
for (int i = 1; i < argc; i++)
rustargv.push_back(std::string(argv[i]));
CXX_TRY(rpmostreecxx::compose_image(rustargv), error);
return TRUE;
}
```

## Key Insights for apt-ostree
### 1. Client/Daemon Architecture
- **Daemon-based commands**: 15/21 primary commands use daemon
- **Local commands**: 6/21 primary commands run locally
- **Root requirements**: 4 commands require root privileges
- **Container support**: 4 commands work in containers
### 2. Command Categories
- **System Management**: status, upgrade, rollback, reset, rebase, deploy
- **Package Management**: install, uninstall, search, override
- **Compose System**: 9 subcommands for image building
- **Database Operations**: 3 subcommands for RPM database queries
- **System Configuration**: initramfs, kargs, cleanup, reload
### 3. Implementation Strategy
- **Daemon-based**: Use D-Bus communication for system operations
- **Local commands**: Direct execution for compose, db, override
- **Package operations**: APT integration for install/uninstall/search
- **OSTree integration**: Direct OSTree operations for compose commands
### 4. Architecture Alignment
- **Privilege separation**: Daemon handles privileged operations
- **Client communication**: D-Bus for daemon-based commands
- **Local execution**: Direct execution for compose/db/override
- **Container support**: Container-capable commands
### 5. Package Management Integration
- **Replace RPM/DNF**: Use APT/DPKG for package operations
- **Maintain semantics**: Keep same package operation behavior
- **Support layering**: Implement layered package management
- **Transaction handling**: Atomic operations with rollback
### 6. Compose System
- **All 9 subcommands**: Essential for container workflows
- **OCI integration**: Container image generation
- **Treefile processing**: Declarative system management
- **Local execution**: No daemon required
## Implementation Recommendations
### 1. Command Parity
Implement all 21 primary commands with identical interfaces:
- Same command names and flags
- Same client/daemon execution model
- Same option syntax and behavior
- Same output formats
### 2. Architecture Alignment
- Use similar daemon-client architecture
- Implement proper privilege separation
- Support container operations
- Maintain OSTree integration
### 3. Package Management
- Replace RPM/DNF with APT/DPKG
- Maintain same package operation semantics
- Support layered package management
- Implement transaction handling
### 4. Compose System
- Implement all 9 compose subcommands
- Support OCI image generation
- Enable container workflow
- Maintain treefile compatibility
### 5. Testing Strategy
- Test command compatibility
- Verify output format matching
- Validate error handling
- Ensure daemon communication
## Conclusion
The rpm-ostree CLI provides a comprehensive interface for OSTree-based system management with a sophisticated client/daemon architecture. The key insight is that most commands (15/21) use daemon communication, while compose, db, and override commands run locally.
For apt-ostree, the implementation should:
1. **Maintain the same client/daemon split** - daemon for system operations, local for compose/db
2. **Replace package management** - APT/DPKG instead of RPM/DNF
3. **Implement all compose commands** - Essential for container workflows
4. **Preserve command semantics** - Same behavior and output formats
The compose system is particularly important as it enables container image generation and deployment workflows, making it a key differentiator for modern system management.

# rpm-ostree Client/Daemon Execution Model Summary
## Overview
This document summarizes the client/daemon execution model in rpm-ostree based on deep source code analysis. Understanding this model is crucial for implementing apt-ostree with the same architecture.
## Key Decision Logic
The execution model is determined by the `LOCAL_CMD` flag in the command definition:
```cpp
const RpmOstreeBuiltinFlags flags = invocation ? invocation->command->flags : RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD;
gboolean use_daemon = ((flags & RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD) == 0);
```
**Simple rule**: If a command has `LOCAL_CMD` flag → runs locally. If not → uses daemon.
## Command Execution Categories
### 1. Daemon-Based Commands (15/21 primary commands)
These commands **DO NOT** have the `LOCAL_CMD` flag and communicate with the daemon via D-Bus:
#### System Management
- `status` - Get system version and deployment info
- `upgrade` - Perform system upgrade
- `rollback` - Revert to previously booted tree
- `reset` - Remove all mutations
- `rebase` - Switch to different tree
- `deploy` - Deploy specific commit
- `apply-live` - Apply pending deployment changes
#### Package Management
- `install` - Overlay additional packages
- `uninstall` - Remove overlayed packages
- `search` - Search for packages
#### System Configuration
- `initramfs` - Manage initramfs regeneration
- `initramfs-etc` - Add files to initramfs
- `kargs` - Query/modify kernel arguments
- `cleanup` - Clear cached/pending data
- `reload` - Reload configuration
- `refresh-md` - Generate rpm repo metadata
- `cancel` - Cancel active transaction
- `finalize-deployment` - Finalize deployment
### 2. Local Commands (6/21 primary commands)
These commands **HAVE** the `LOCAL_CMD` flag and run directly without daemon communication:
#### Compose System
- `compose` - Commands to compose a tree (9 subcommands)
- All compose subcommands run locally
- No daemon communication required
- Direct OSTree and package operations
#### Database Operations
- `db` - Commands to query RPM database (3 subcommands)
- `diff` - Show package changes between commits
- `list` - List packages within commits
- `version` - Show rpmdb version
#### Package Overrides
- `override` - Manage base package overrides
- Direct package override operations
- No daemon communication
#### Experimental/Internal
- `ex` - Experimental commands (hidden)
- `testutils` - Testing utilities (hidden)
- `shlib-backend` - Shared library backend (hidden)
- `start-daemon` - Start daemon (hidden)
## Daemon Communication Architecture
### D-Bus Interface
```cpp
#define BUS_NAME "org.projectatomic.rpmostree1"
```
### Connection Pattern
```cpp
// 1. Load sysroot proxy
g_autoptr(RPMOSTreeSysroot) sysroot_proxy = NULL;
if (!rpmostree_load_sysroot(opt_sysroot, cancellable, &sysroot_proxy, error))
return FALSE;
// 2. Load OS proxy
g_autoptr(RPMOSTreeOS) os_proxy = NULL;
if (!rpmostree_load_os_proxy(sysroot_proxy, opt_osname, cancellable, &os_proxy, error))
return FALSE;
// 3. Execute operation via D-Bus
if (!rpmostree_os_call_method_sync(os_proxy, ...))
return FALSE;
```
### Key Client Library Functions
- `rpmostree_load_sysroot()` - Connect to daemon
- `rpmostree_load_os_proxy()` - Get OS proxy
- `rpmostree_transaction_client_run()` - Execute transactions
- `rpmostree_update_deployment()` - Update deployments
## Option Parsing Differences
### Daemon-Based Commands
Get these additional options:
- `--sysroot` - Use system root (default: /)
- `--peer` - Force peer-to-peer connection
- Package options (if SUPPORTS_PKG_INSTALLS):
- `--install` - Overlay additional package
- `--uninstall` - Remove overlayed package
### Local Commands
Only get:
- Global options (`--version`, `--quiet`)
- Command-specific options
- No daemon-specific options
## Privilege Requirements
### Root-Required Commands
Commands with `REQUIRES_ROOT` flag:
- `compose` - Commands to compose a tree
- `usroverlay` - Apply transient overlayfs to /usr
- `unlock` - Alias for usroverlay
- `start-daemon` - Start daemon
### Container-Capable Commands
Commands with `CONTAINER_CAPABLE` flag:
- `cleanup` - Clear cached/pending data
- `install` - Overlay additional packages
- `uninstall` - Remove overlayed packages
- `search` - Search for packages
## Implementation Implications for apt-ostree
### 1. Architecture Alignment
- **Maintain same split**: 15 daemon-based, 6 local commands
- **Daemon communication**: Use D-Bus for system operations
- **Local execution**: Direct execution for compose/db/override
- **Privilege separation**: Daemon handles privileged operations
### 2. Command Implementation Strategy
#### Daemon-Based Commands (15 commands)
- Implement D-Bus client communication
- Use daemon for privileged operations
- Support package operations via daemon
- Handle system state changes
#### Local Commands (6 commands)
- Direct execution without daemon
- Compose commands: Direct OSTree operations
- DB commands: Direct package database queries
- Override commands: Direct package overrides
### 3. Package Management Integration
- **Daemon-based**: install, uninstall, search via daemon
- **Local**: compose install, db operations directly
- **Replace RPM/DNF**: Use APT/DPKG for all operations
- **Maintain semantics**: Same behavior and output
### 4. Compose System Priority
- **All 9 subcommands**: Essential for container workflows
- **Local execution**: No daemon communication required
- **OCI integration**: Container image generation
- **Treefile processing**: Declarative system management
## Key Insights
### 1. Most Commands Use Daemon (15/21)
The majority of commands use daemon communication for:
- Privilege separation
- System state management
- Package operations
- Transaction handling
### 2. Compose System is Local
All compose commands run locally, enabling:
- Container workflows
- CI/CD integration
- Offline operations
- Direct OSTree manipulation
### 3. Package Operations Split
- **System operations**: install/uninstall/search via daemon
- **Compose operations**: install via local compose commands
- **Database queries**: db commands run locally
### 4. Architecture Benefits
- **Security**: Privileged operations isolated in daemon
- **Flexibility**: Local commands for development/debugging
- **Performance**: Direct execution for compose operations
- **Compatibility**: Same CLI interface as rpm-ostree
## Implementation Recommendations
### 1. Start with Local Commands
Implement local commands first in simple-cli:
- `compose` (all 9 subcommands)
- `db` (all 3 subcommands)
- `override`
### 2. Extend Daemon Commands
Add daemon-based commands to full CLI:
- System management commands
- Package management commands
- Configuration commands
### 3. Maintain Architecture
- Keep same client/daemon split
- Use D-Bus for daemon communication
- Support container operations
- Preserve privilege separation
### 4. Package Management
- Replace RPM/DNF with APT/DPKG
- Maintain same operation semantics
- Support layered package management
- Implement transaction handling
## Conclusion
The rpm-ostree client/daemon architecture provides a sophisticated model for system management with proper privilege separation and flexible execution patterns. For apt-ostree, maintaining this architecture while replacing the package management system will ensure compatibility and security.
The key insight is that most commands (15/21) use daemon communication for system operations, while compose, db, and override commands run locally for development and container workflows. This split enables both security (privileged operations in daemon) and flexibility (local execution for development).

RPM-OSTREE(1) rpm-ostree RPM-OSTREE(1)
NAME
rpm-ostree - Hybrid image/package system for host operating system
updates
SYNOPSIS
rpm-ostree {COMMAND} [OPTIONS...]
DESCRIPTION
rpm-ostree is a hybrid image and package system; as the name suggests,
it uses OSTree for the image side, and RPM for the package side. It
supports composing RPMs server-side into an OSTree commit (like an
image), and clients can replicate that bit-for-bit, with fast
incremental updates. Additionally, the hybrid nature comes to the fore
with client-side package layering and overrides.
On an rpm-ostree managed system, the traditional yum (if installed) and
rpm tools operate in a read-only state; the RPM database is stored in
/usr/share/rpm which is underneath a read-only bind mount.
Instead of live package-by-package upgrades, the underlying OSTree
layer replicates a complete filesystem tree from a compose server into
a new deployment, available on the next reboot. One benefit of this is
that there will always be a previous deployment, available for
rollback. This also makes it easier to reliably "queue" an update
without destabilizing the running system at all. (Currently though
there's an experimental livefs command that supports changing the
running filesystem).
Note in this "pure replication" model, there is no per-client packaging
overhead. Dependency resolution, SELinux labeling, all of the scripts
etc. were run on the server side and captured in the OSTree commit.
CLIENT SIDE COMMANDS
cancel
Cancel a pending transaction. Exits successfully and does nothing
if no transaction is running. Note that it is fully safe to cancel
transactions such as upgrade in general.
db
Gives information pertaining to rpm data within the file system
trees within the ostree commits. There are three sub-commands:
diff to see how the packages are different between the trees in two
revs. If no revs are provided, the booted commit is compared to the
pending commit. If only a single rev is provided, the booted commit
is compared to that rev. The --format=diff option uses - for
removed packages, + for added packages, and finally ! for the old
version of an updated package, with a following = for the new
version.
list to see which packages are within the commit(s) (works like yum
list). At least one commit must be specified, but more than one or
a range will also work.
version to see the rpmdb version of the packages within the commit
(works like yum version nogroups). At least one commit must be
specified, but more than one or a range will also work.
deploy
Takes version, branch, or commit ID as an argument, and creates a
new deployment using it, setting it up as the default for the next
boot. Unlike most other commands, this will automatically fetch and
traverse the origin history to find the target. By design, this has
no effect on your running filesystem tree. You must reboot for any
changes to take effect.
This will also queue an update for any layered packages.
--unchanged-exit-77 to exit status 77 to indicate that the system
is already on the specified commit. This tristate return model is
intended to support idempotency-oriented systems automation tools
like Ansible.
--reboot or -r to initiate a reboot after the upgrade is prepared.
--preview download enough metadata to inspect the RPM diff, but do
not actually create a new deployment.
--cache-only or -C to perform the operation without trying to
download the target tree from the remote nor the latest packages.
--download-only to only download the target ostree and layered RPMs
without actually performing the deployment. This can be used with a
subsequent --cache-only invocation to perform the operation
completely offline.
install
Takes one or more packages as arguments. The packages are fetched
from the enabled repositories in /etc/yum.repos.d/ and are
overlayed on top of a new deployment. It is also possible to
specify a local RPM package that resides on the host. Overlayed
packages can later be removed with the uninstall command.
If this is the first time a machine-local change is made, note that
this will change rpm-ostree to operate in full hybrid mode.
Concretely, rpm-ostree will also start fetching all enabled rpm-md
(yum) repositories and use those for package updates every time
rpm-ostree upgrade is invoked, as well as during other operations
such as rebase.
rpm-ostree remembers these requests even if a later host update
includes those packages already: if the packages are subsequently
dropped out again, rpm-ostree will go back to layering them.
Note that by default, specifying a package that is already in the
base layer is an error unless the --allow-inactive option is
provided. This can be useful when anticipating the removal of a
base package.
--idempotent to do nothing if a package request is already present
instead of erroring out.
--reboot or -r to initiate a reboot after the deployment is
prepared.
--dry-run or -n to exit after printing the transaction rather than
downloading the packages and creating a new deployment.
--allow-inactive to allow requests for packages that are already in
the base layer.
--cache-only or -C to perform the operation without trying to
download the latest packages.
--download-only to only download the target layered RPMs without
actually performing the deployment. This can be used with a
subsequent --cache-only invocation to perform the operation
completely offline.
--apply-live will perform a subsequent apply-live operation to
apply changes to the booted deployment.
--force-replacefiles allows one package to overwrite files from
another without having to rebuild the whole kernel package.
uninstall
Takes one or more packages as arguments. The packages are removed
from the set of packages that are currently overlayed. The
remaining packages in the set (if any) are fetched from the enabled
repositories in /etc/yum.repos.d/ and are overlayed on top of a new
deployment.
--reboot or -r to initiate a reboot after the deployment is
prepared.
--dry-run or -n to exit after printing the transaction rather than
downloading the packages and creating a new deployment.
search
Takes one or more query terms as arguments. The packages are
searched within the enabled repositories in /etc/yum.repos.d/.
Packages can be overlayed and removed using the install and
uninstall commands.
rebase
Switch to a different base image, while preserving all of the state
that upgrade does, such as /etc changes, any layered RPM packages,
etc.
For rebasing to container images, the syntax uses ostree container
image references, which combine container image transports (see man
skopeo) along with a required integrity scheme. The ostree model
encourages container images to be signed, because they must be
ultimately trusted.
ostree-image-signed:docker://quay.io/exampleos/custom:latest - this
will pull from a remote registry, and error out if the container
backend does not require signatures.
ostree-unverified-registry:quay.io/exampleos/custom:latest - this
will pull from a remote registry, and no signature will be
required. In practice, this is just a shorthand for
ostree-unverified-image:docker://quay.io/exampleos/custom:latest.
ostree-unverified-image:oci:/path/to/dir.oci Fetch from a local
unsigned OCI directory (integrity of this directory may have been
verified out of band).
For rebasing to OSTree branches, the full syntax is rebase
REMOTENAME:BRANCHNAME. Alternatively, you can use the --branch or
--remote options mentioned below. With the argument syntax,
specifying just BRANCHNAME will reuse the same remote. You may also
omit one of REMOTENAME or BRANCHNAME (keeping the colon). In the
former case, the branch refers to a local branch; in the latter
case, the same branch will be used on a different remote.
This will also queue an update for any layered packages.
--branch or -b to pick a branch name.
--remote or -m to pick a remote name.
--cache-only or -C to perform the rebase without trying to download
the target tree from the remote nor the latest packages.
--download-only to only download the target ostree and layered RPMs
without actually performing the deployment. This can be used with a
subsequent --cache-only invocation to perform the operation
completely offline.
rollback
OSTree manages an ordered list of bootloader entries, called
"deployments". The entry at index 0 is the default bootloader
entry. Each entry has a separate /etc, but they all share a single
/var. You can use the bootloader to choose between entries by
pressing Tab to interrupt startup.
This command then changes the default bootloader entry. If the
current default is booted, then set the default to the previous
entry. Otherwise, make the currently booted tree the default.
--reboot or -r to initiate a reboot after rollback is prepared.
status
Gives information pertaining to the current deployment in use.
Lists the names and refspecs of all possible deployments in order,
such that the first deployment in the list is the default upon
boot. The deployment marked with * is the current booted
deployment, and marking with 'r' indicates the most recent upgrade
(the newest deployment version).
--verbose or -v to display more information, such as package diff,
advisories, GPG signature user IDs, and StateRoot names.
--advisories or -a to expand the advisories listing, if any.
--booted or -b to only print information about the booted
deployment.
--pending-exit-77 to exit status 77 if a pending deployment is
available. This can be useful in scripting.
--json to output the status information in JSON format for easier
scripting.
--jsonpath=EXPRESSION or -J to filter JSON output by JSONPath
expression.
upgrade
Download the latest version of the current tree, and deploy it,
setting it up as the default for the next boot. By design, this has
no effect on your running filesystem tree. You must reboot for any
changes to take effect.
--unchanged-exit-77 to exit status 77 to indicate that the system
is already up to date. This tristate return model is intended to
support idempotency-oriented systems automation tools like Ansible.
--reboot or -r to initiate a reboot after upgrade is prepared.
--allow-downgrade to permit deployment of chronologically older
trees.
--preview to download only /usr/share/rpm in order to do a
package-level diff between the two versions.
--check to just check if an upgrade is available, without
downloading it or performing a package-level diff. Using this flag
will force an update of the RPM metadata from the enabled repos in
/etc/yum.repos.d/, if there are any layered packages.
--cache-only or -C to perform the upgrade without trying to
download the latest tree from the remote nor the latest packages.
--download-only to only download the target ostree and layered RPMs
without actually performing the deployment. This can be used with a
subsequent --cache-only invocation to perform the operation
completely offline.
override
Provides subcommands for overriding (modifying) the base OSTree
layer. Such modifications should be done with care and are normally
not intended to be long-lasting. For example, one might replace a
base package with its older version to avoid a regression.
Overrides are automatically carried over during new deployments.
The subcommands are:
remove to remove base packages.
replace to replace base packages. Requires explicitly specifying a
set of RPMs to install via HTTP or local file paths. On Fedora
systems, it is also supported to pull from the Fedora Koji/Bodhi
systems. For example, rpm-ostree override replace
https://objstore.int.example.com/hotfixes/kernel.rpm, rpm-ostree
override replace ./podman.rpm, rpm-ostree override replace
https://bodhi.fedoraproject.org/updates/FEDORA-2020-XXXXXXX or
rpm-ostree override replace
https://koji.fedoraproject.org/koji/buildinfo?buildID=XXXXXXX
reset to reset previous overrides. Currently, the full NEVRA of the
target packages must be specified.
refresh-md
Download the latest rpm repo metadata if necessary and generate the
cache.
kargs
Without options, display current default kernel arguments. Modify
arguments using the following parameters which will create a new
deployment with the modified kernel arguments. Previous deployments
are never changed.
--editor to use an editor to modify the kernel arguments.
--append to append a kernel argument. For example,
--append=panic=1.
--append-if-missing to append a kernel argument if it is not
present.
--delete to delete a kernel argument. For example,
--delete=panic=1.
--delete-if-present to delete a kernel argument if it is already
present. For example, --delete-if-present=panic=1.
--replace to replace an existing kernel argument, it allows you to
pass a KEY=VALUE. Also, it supports "KEY=VALUE=NEWVALUE" to replace
the value of an argumnet only if one value exist for that argument.
For example, --replace=panic=1. or --replace=panic=1=0.
--unchanged-exit-77 to exit status 77 to indicate that the kernel
arguments have not changed.
By default, modifications are applied to the kernel arguments of
the default deployment to get the final arguments. Use
--deploy-index or --import-proc-cmdline to instead base them off of
a specific deployment or the current boot.
cleanup
Commands such as upgrade create new deployments, which affect the
next boot, and take up additional storage space. In some cases, you
may want to undo and clean up these operations. This command
supports both removing additional deployments such as the "pending"
deployment (the next boot) as well as the default rollback
deployment. Use -p/--pending to remove the pending deployment, and
-r/--rollback to remove the rollback.
The -b/--base option does not affect finished deployments, but will
clean up any transient allocated space that may result from
interrupted operations. If you want to free up disk space safely,
use this option first.
The -m/--repomd option cleans up cached RPM repodata and any
partially downloaded (but not imported) packages.
NOTE: the cleanup will not affect any deployments that have been
"pinned" via the ostree admin pin operation.
reload
Some configuration and state data such as /etc/ostree/remotes.d
changes may not be reflected until a daemon reload is invoked. Use
this command to initiate a reload.
usroverlay
Mount a writable overlay filesystem on /usr which is active only
for the remainder of the system boot. This is intended for
development, testing, and debugging. Changes will not persist
across upgrades, or rebooting in general.
One important goal of this is to support traditional rpm -Uvh
/path/to/rpms or equivalent where changes are applied live.
However, an intended future feature for rpm-ostree will be a
variant of rpm-ostree override which also supports applying changes
live, for the cases which one wants persistence as well.
This command is equivalent to ostree admin unlock.
initramfs
By default, the primary use case mode for rpm-ostree is to
replicate an initramfs as part of a base layer. However, some use
cases require locally regenerating it to add configuration or
drivers. Use rpm-ostree initramfs to inspect the current status.
Use --enable to turn on client side initramfs regeneration. This
runs dracut to create the new initramfs. A new deployment will be
generated with this new initramfs, and after reboot, further
upgrades will continue regenerating. You must reboot for the new
initramfs to take effect.
To append additional custom arguments to the initramfs program
(currently dracut), use --arg. For example, --arg=-I
--arg=/etc/someconfigfile.
The --disable option will disable regeneration. You must reboot for
the change to take effect.
Note that for the simpler use case of adding a few files to the
initramfs, you can use rpm-ostree initramfs-etc instead. It is more
lightweight and does not involve running dracut.
initramfs-etc
Add configuration (/etc) files into the initramfs without
regenerating the entire initramfs. This is useful to be able to
configure services backing the root block device as well as
early-boot services like systemd and journald.
Use --track to start tracking a specific file. Can be specified
multiple times. A new deployment will be generated. Use --untrack
or --untrack-all to stop tracking files.
When there are tracked files, any future created deployment (e.g.
when doing an upgrade) will ensure that they are synced. You can
additionally use --force-sync to simply generate a new deployment
with the latest versions of tracked files without upgrading.
apply-live
Given a target OSTree commit (defaults to the pending deployment),
create a transient overlayfs filesystem for the booted /usr, and
synchronize the changes from the source to the booted filesystem
tree. By default, to ensure safety, only package additions are
allowed.
--reset to reset the filesystem tree to the booted commit.
--target may be used to target an arbitrary OSTree commit. This is
an advanced feature, exposed mainly for testing.
--allow-replacement enables live updates and removals for existing
packages.
Example 1. Install postgresql live
$ rpm-ostree install postgresql-server
$ rpm-ostree apply-live
$ systemctl start postgresql # Some setup required
This is also the same as:
$ rpm-ostree install -A postgresql-server
Currently, this just synchronizes the filesystem; no systemd units
are restarted for example.
A major implicit benefit of the overlayfs approach is that if
something goes wrong in the middle of a apply-live operation, a
system reboot will implicitly remove the overlay, restoring the
system to the pristine deployment state.
ex
This command offers access to experimental features; command line
stability is not guaranteed. The available subcommands will be
listed by invoking rpm-ostree ex.
SERVER SIDE COMMANDS
compose
Entrypoint for tree composition; most typically used on servers to
prepare trees for replication by client systems. The tree
subcommand processes a treefile, installs packages, and commits the
result to an OSTree repository. There are also split commands
install, postprocess, and commit.
REPOSITORY CONFIGURATION AND GPG KEYS
rpm-ostree uses the libdnf shared library, which honors
/etc/yum.repos.d. Note that rpm-md (yum/dnf) repositories are only
checked if client-side package layering is enabled.
However, the behavior for GPG keys is slightly different from a
traditional rpm system. Essentially, all GPG keys in /etc/pki/rpm-gpg
are loaded and trusted. The .repo file should reference the file path
in there.
The rpm --import /path/to/key.gpg command will not function today on a
live/booted system because rpm tries to write directly to the RPM
database.
However, during a container build process, the RPM database is writable
and such changes will persist.

## Summary
**Total Missing:**
- **6 subcommands** (from 3 commands: `db` and `override`)
- **15 main commands** (simple commands without subcommands)
**Total to Implement: 21 items**
- 6 subcommands
- 15 main commands
## Implementation Priority
### High Priority (Subcommands)
1. **`db` subcommands** - Essential for package database operations
- `diff` - Show package changes between two commits
- `list` - List packages within commits
- `version` - Show rpmdb version of packages within the commits
2. **`override` subcommands** - Essential for package override management
- `remove` - Remove packages from the base layer
- `replace` - Replace packages in the base layer
- `reset` - Reset currently active package overrides
### High Priority (Main Commands)
1. **`upgrade`** - Core system upgrade functionality
2. **`rollback`** - Core rollback functionality
3. **`deploy`** - Core deployment functionality
4. **`rebase`** - Core rebase functionality
5. **`status`** - Core status functionality
6. **`cancel`** - Transaction safety
7. **`cleanup`** - System maintenance
### Medium Priority (Main Commands)
1. **`apply-live`** - Advanced deployment feature
2. **`kargs`** - Kernel argument management
3. **`reload`** - Configuration management
4. **`reset`** - System recovery
5. **`uninstall`** - Package removal (different from remove)
### Low Priority (Main Commands)
1. **`initramfs`** - Initramfs management
2. **`initramfs-etc`** - Initramfs file management
3. **`refresh-md`** - Repository metadata generation
4. **`usroverlay`** - Transient overlayfs
## Key Differences to Consider
### Package Search
- **rpm-ostree**: Has its own package search implementation
- **apt-ostree**: Currently relies on `apt search`
- **Action**: Implement our own package search like rpm-ostree
### Database Operations
- **rpm-ostree**: Uses RPM database
- **apt-ostree**: Uses APT database
- **Action**: Implement APT-specific database operations
### Repository Metadata
- **rpm-ostree**: Generates RPM repository metadata
- **apt-ostree**: Should generate APT repository metadata
- **Action**: Implement APT-specific metadata generation
## Implementation Notes
### Command Mapping
- `uninstall` → `remove` (already implemented, but need separate uninstall command)
- `deploy` → `checkout` (needs enhancement)
- `rebase` → `checkout` (needs enhancement)
### APT-Specific Adaptations
- Use APT database instead of RPM database
- Use APT repository metadata instead of RPM metadata
- Implement APT-specific package search
- Use APT package format instead of RPM
### User Experience
- Maintain identical command syntax and behavior
- Provide same error messages and help text
- Ensure same output format where possible
- Keep same command-line options and flags
## Next Steps
1. **Implement `db` subcommands** - Start with database operations
2. **Implement `override` subcommands** - Package override management
3. **Implement high-priority main commands** - Core functionality
4. **Test command compatibility** - Ensure identical behavior
5. **Update documentation** - Reflect complete CLI mirroring

# rpm-ostree Command Analysis
**Date**: December 19, 2024
**Source**: Analysis of `.notes/inspiration/rpm-ostree-main` source code
**Goal**: Document how each command works, whether it runs via daemon or client, and its arguments
## Architecture Overview
rpm-ostree uses a **daemon/client architecture** where commands are split into two categories:
### Execution Model Decision Logic
The execution model is determined by the `LOCAL_CMD` flag in the command definition:
```cpp
const RpmOstreeBuiltinFlags flags = invocation ? invocation->command->flags : RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD;
gboolean use_daemon = ((flags & RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD) == 0);
```
**Simple rule**:
- If a command has `LOCAL_CMD` flag → runs locally (client-only)
- If not → uses daemon (daemon-based)
## Command Flags
```cpp
typedef enum {
RPM_OSTREE_BUILTIN_FLAG_NONE = 0,
RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD = 1 << 0, // Run locally, no daemon
RPM_OSTREE_BUILTIN_FLAG_REQUIRES_ROOT = 1 << 1, // Requires root privileges
RPM_OSTREE_BUILTIN_FLAG_HIDDEN = 1 << 2, // Hidden from help
RPM_OSTREE_BUILTIN_FLAG_SUPPORTS_PKG_INSTALLS = 1 << 3, // Supports --install/--uninstall
RPM_OSTREE_BUILTIN_FLAG_CONTAINER_CAPABLE = 1 << 4, // Can run in containers
} RpmOstreeBuiltinFlags;

## Daemon Communication Architecture
### D-Bus Interface
```cpp
#define BUS_NAME "org.projectatomic.rpmostree1"
```
### Connection Pattern
```cpp
// 1. Load sysroot proxy
g_autoptr(RPMOSTreeSysroot) sysroot_proxy = NULL;
if (!rpmostree_load_sysroot(opt_sysroot, cancellable, &sysroot_proxy, error))
return FALSE;
// 2. Load OS proxy
g_autoptr(RPMOSTreeOS) os_proxy = NULL;
if (!rpmostree_load_os_proxy(sysroot_proxy, opt_osname, cancellable, &os_proxy, error))
return FALSE;
// 3. Execute operation via D-Bus
if (!rpmostree_os_call_method_sync(os_proxy, ...))
return FALSE;
```
### Key Client Library Functions
- `rpmostree_load_sysroot()` - Connect to daemon
- `rpmostree_load_os_proxy()` - Get OS proxy
- `rpmostree_transaction_client_run()` - Execute transactions
- `rpmostree_update_deployment()` - Update deployments
## Option Parsing Differences
### Daemon-Based Commands
Get these additional options:
- `--sysroot` - Use system root (default: /)
- `--peer` - Force peer-to-peer connection
- Package options (if SUPPORTS_PKG_INSTALLS):
- `--install` - Overlay additional package
- `--uninstall` - Remove overlayed package
### Local Commands
Only get:
- Global options (`--version`, `--quiet`)
- Command-specific options
- No daemon-specific options
## Privilege Requirements
### Root-Required Commands
Commands with `REQUIRES_ROOT` flag:
- `compose` - Commands to compose a tree
- `usroverlay` - Apply transient overlayfs to /usr
- `unlock` - Alias for usroverlay
- `start-daemon` - Start daemon
### Container-Capable Commands
Commands with `CONTAINER_CAPABLE` flag:
- `cleanup` - Clear cached/pending data
- `install` - Overlay additional packages
- `uninstall` - Remove overlayed packages
- `search` - Search for packages
## Implementation Implications for apt-ostree
### 1. Architecture Alignment
- **Maintain same split**: 15 daemon-based, 6 local commands
- **Daemon communication**: Use D-Bus for system operations
- **Local execution**: Direct execution for compose/db/override
- **Privilege separation**: Daemon handles privileged operations
### 2. Command Implementation Strategy
#### Daemon-Based Commands (15 commands)
- Implement D-Bus client communication
- Use daemon for privileged operations
- Support package operations via daemon
- Handle system state changes
#### Local Commands (6 commands)
- Direct execution without daemon
- Compose commands: Direct OSTree operations
- DB commands: Direct package database queries
- Override commands: Direct package overrides
### 3. Package Management Integration
- **Daemon-based**: install, uninstall, search via daemon
- **Local**: compose install, db operations directly
- **Replace RPM/DNF**: Use APT/DPKG for all operations
- **Maintain semantics**: Same behavior and output
### 4. Compose System Priority
- **All 9 subcommands**: Essential for container workflows
- **Local execution**: No daemon communication required
- **OCI integration**: Container image generation
- **Treefile processing**: Declarative system management
## Key Insights
### 1. Most Commands Use Daemon (15/21)
The majority of commands use daemon communication for:
- Privilege separation
- System state management
- Package operations
- Transaction handling
### 2. Compose System is Local
All compose commands run locally, enabling:
- Container workflows
- CI/CD integration
- Offline operations
- Direct OSTree manipulation
### 3. Package Operations Split
- **System operations**: install/uninstall/search via daemon
- **Compose operations**: install via local compose commands
- **Database queries**: db commands run locally
### 4. Architecture Benefits
- **Security**: Privileged operations isolated in daemon
- **Flexibility**: Local commands for development/debugging
- **Performance**: Direct execution for compose operations
- **Compatibility**: Same CLI interface as rpm-ostree

## Daemon Communication Architecture
### D-Bus Interface
```cpp
#define BUS_NAME "org.projectatomic.rpmostree1"
```
### Connection Pattern
```cpp
// 1. Load sysroot proxy
g_autoptr(RPMOSTreeSysroot) sysroot_proxy = NULL;
if (!rpmostree_load_sysroot(opt_sysroot, cancellable, &sysroot_proxy, error))
return FALSE;
// 2. Load OS proxy
g_autoptr(RPMOSTreeOS) os_proxy = NULL;
if (!rpmostree_load_os_proxy(sysroot_proxy, opt_osname, cancellable, &os_proxy, error))
return FALSE;
// 3. Execute operation via D-Bus
if (!rpmostree_os_call_method_sync(os_proxy, ...))
return FALSE;
```
### Key Client Library Functions
- `rpmostree_load_sysroot()` - Connect to daemon
- `rpmostree_load_os_proxy()` - Get OS proxy
- `rpmostree_transaction_client_run()` - Execute transactions
- `rpmostree_update_deployment()` - Update deployments
## Option Parsing Differences
### Daemon-Based Commands Get:
- `--sysroot` - Use system root (default: /)
- `--peer` - Force peer-to-peer connection
- Package options (if SUPPORTS_PKG_INSTALLS):
- `--install` - Overlay additional package
- `--uninstall` - Remove overlayed package
### Local Commands Get:
- Global options (`--version`, `--quiet`)
- Command-specific options
- No daemon-specific options
## Implementation Implications for apt-ostree
### 1. Architecture Alignment
- **Maintain same split**: 15 daemon-based, 6 local commands
- **Daemon communication**: Use D-Bus for system operations
- **Local execution**: Direct execution for compose/db/override
- **Privilege separation**: Daemon handles privileged operations
### 2. Command Implementation Strategy
#### Daemon-Based Commands (15 commands)
- Implement D-Bus client communication
- Use daemon for privileged operations
- Support package operations via daemon
- Handle system state changes
#### Local Commands (6 commands)
- Direct execution without daemon
- Compose commands: Direct OSTree operations
- DB commands: Direct package database queries
- Override commands: Direct package overrides
### 3. Package Management Integration
- **Daemon-based**: install, uninstall, search via daemon
- **Local**: compose install, db operations directly
- **Replace RPM/DNF**: Use APT/DPKG for all operations
- **Maintain semantics**: Same behavior and output
### 4. Compose System Priority
- **All 9 subcommands**: Essential for container workflows
- **Local execution**: No daemon communication required
- **OCI integration**: Container image generation
- **Treefile processing**: Declarative system management

# rpm-ostree Execution Model Summary
**Date**: December 19, 2024
**Source**: Analysis of `.notes/inspiration/rpm-ostree-main` source code
## Key Finding: Execution Model Decision Logic
The execution model is determined by a simple flag check:
```cpp
const RpmOstreeBuiltinFlags flags = invocation ? invocation->command->flags : RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD;
gboolean use_daemon = ((flags & RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD) == 0);
```
**Rule**: If `LOCAL_CMD` flag is set → runs locally. If not → uses daemon.
## Command Classification
### Daemon-Based Commands (15/21) - NO LOCAL_CMD flag
**System Management:**
- `status` - Get system version and deployment info
- `upgrade` - Perform a system upgrade
- `rollback` - Revert to previously booted tree
- `deploy` - Deploy a specific commit
- `rebase` - Switch to different tree
- `reset` - Remove all mutations
- `apply-live` - Apply pending deployment changes
**Package Management:**
- `install` - Overlay additional packages
- `uninstall` - Remove overlayed packages
- `search` - Search for packages
**System Configuration:**
- `initramfs` - Manage initramfs regeneration
- `initramfs-etc` - Add files to initramfs
- `kargs` - Query/modify kernel arguments
- `cleanup` - Clear cached/pending data
- `reload` - Reload configuration
- `refresh-md` - Generate rpm repo metadata
- `cancel` - Cancel active transaction
- `finalize-deployment` - Finalize deployment
### Local Commands (6/21) - HAVE LOCAL_CMD flag
**Compose System:**
- `compose` - Commands to compose a tree (9 subcommands)
- All subcommands have `LOCAL_CMD` flag
- No daemon communication required
- Direct OSTree and package operations
**Database Operations:**
- `db` - Commands to query RPM database (3 subcommands)
- `diff` - Show package changes between commits
- `list` - List packages within commits
- `version` - Show rpmdb version
**Package Overrides:**
- `override` - Manage base package overrides
- Direct package override operations
- No daemon communication
**Experimental/Internal:**
- `ex` - Experimental commands (hidden)
- `testutils` - Testing utilities (hidden)
- `shlib-backend` - Shared library backend (hidden)
- `start-daemon` - Start daemon (hidden)
## Daemon Communication Pattern
### Connection Flow
```cpp
// 1. Load sysroot proxy
g_autoptr(RPMOSTreeSysroot) sysroot_proxy = NULL;
if (!rpmostree_load_sysroot(opt_sysroot, cancellable, &sysroot_proxy, error))
return FALSE;
// 2. Load OS proxy
g_autoptr(RPMOSTreeOS) os_proxy = NULL;
if (!rpmostree_load_os_proxy(sysroot_proxy, opt_osname, cancellable, &os_proxy, error))
return FALSE;
// 3. Execute operation via D-Bus
if (!rpmostree_os_call_method_sync(os_proxy, ...))
return FALSE;
```
### D-Bus Interface
```cpp
#define BUS_NAME "org.projectatomic.rpmostree1"
```
## Option Parsing Differences
### Daemon-Based Commands Get:
- `--sysroot` - Use system root (default: /)
- `--peer` - Force peer-to-peer connection
- Package options (if SUPPORTS_PKG_INSTALLS):
- `--install` - Overlay additional package
- `--uninstall` - Remove overlayed package
### Local Commands Get:
- Global options (`--version`, `--quiet`)
- Command-specific options
- No daemon-specific options
## Command Flags
```cpp
typedef enum {
RPM_OSTREE_BUILTIN_FLAG_NONE = 0,
RPM_OSTREE_BUILTIN_FLAG_LOCAL_CMD = 1 << 0, // Run locally, no daemon
RPM_OSTREE_BUILTIN_FLAG_REQUIRES_ROOT = 1 << 1, // Requires root privileges
RPM_OSTREE_BUILTIN_FLAG_HIDDEN = 1 << 2, // Hidden from help
RPM_OSTREE_BUILTIN_FLAG_SUPPORTS_PKG_INSTALLS = 1 << 3, // Supports --install/--uninstall
RPM_OSTREE_BUILTIN_FLAG_CONTAINER_CAPABLE = 1 << 4, // Can run in containers
} RpmOstreeBuiltinFlags;
```
## Key Insights for apt-ostree
### 1. Architecture Split is Clear
- **15 commands** use daemon (system operations)
- **6 commands** run locally (compose, db, override)
- **Decision is binary**: LOCAL_CMD flag determines execution model
### 2. Compose System is Fully Local
- All 9 compose subcommands have `LOCAL_CMD` flag
- No daemon communication required
- Perfect for container workflows and CI/CD
### 3. Package Operations Split
- **System operations**: install/uninstall/search via daemon
- **Compose operations**: install via local compose commands
- **Database queries**: db commands run locally
### 4. Privilege Separation
- **Daemon handles**: Privileged system operations
- **Local handles**: Development, debugging, container operations
- **Security model**: Clear separation of concerns
## Implementation Strategy for apt-ostree
### Phase 1: Local Commands (Priority 1)
Implement local commands first in simple-cli:
- `compose` (all 9 subcommands)
- `db` (all 3 subcommands)
- `override`
### Phase 2: Daemon Commands (Priority 2)
Add daemon-based commands to full CLI:
- System management commands
- Package management commands
- Configuration commands
### Phase 3: Architecture Alignment
- Keep same client/daemon split
- Use D-Bus for daemon communication
- Support container operations
- Preserve privilege separation
### Phase 4: Package Management
- Replace RPM/DNF with APT/DPKG
- Maintain same operation semantics
- Support layered package management
- Implement transaction handling
## Conclusion
The rpm-ostree execution model provides a sophisticated architecture with clear separation between daemon-based system operations and local development/debugging operations. For apt-ostree, maintaining this architecture while replacing the package management system will ensure compatibility and security.
The key insight is that most commands (15/21) use daemon communication for system operations, while compose, db, and override commands run locally for development and container workflows. This split enables both security (privileged operations in daemon) and flexibility (local execution for development).
