🚀 CRITICAL COMMANDS NOW FULLY FUNCTIONAL:

✅ apt-ostree compose tree - Real tree composition with APT package installation and OSTree commits
✅ apt-ostree db search - Real APT package search for deb-orchestrator integration
✅ apt-ostree db show - Real package metadata display functionality
✅ apt-ostree compose container-encapsulate - Real OCI-compliant container image generation

🔧 TECHNICAL ACHIEVEMENTS:
- Real treefile parsing with YAML support (serde_yaml)
- Build environment setup with isolated chroots
- APT package installation in build environment
- Real OSTree repository initialization and commit creation
- OCI container image generation with proper manifests
- Comprehensive error handling and progress reporting

📦 DEPENDENCIES ADDED:
- serde_yaml for treefile parsing
- tar for container archive creation
- chrono for timestamp generation in OCI config

🎯 IMPACT:
- deb-bootc-compose: ✅ READY - Full OSTree tree composition and container generation
- deb-orchestrator: ✅ READY - Package search and metadata display
- deb-mock: 🟡 PARTIALLY READY - Core functionality working

This represents a complete transformation from placeholder implementations to fully functional
commands that can be used in production CI/CD environments for Debian-based OSTree systems.

$ rpm-ostree compose build-chunked-oci --help
Generate a "chunked" OCI archive from an input rootfs
Usage: rpm-ostree [OPTIONS] --bootc --output <OUTPUT>
Options:
--rootfs <ROOTFS>
Path to the source root filesystem tree
--from <FROM>
Use the provided image (in containers-storage)
--bootc
If set, configure the output OCI image to be a bootc container. At the current time this option is required
--format-version <FORMAT_VERSION>
The format version. Version `1` creates OCI (tar) layers sparsely, meaning parent directories may be omitted from the tar stream. Version `2` ensures that all parent directories in all layers are present in the tar stream. Default value is `1` for backward compatibility [default: 1]
--max-layers <MAX_LAYERS>
Maximum number of layers to use. The default value of 64 is chosen to balance splitting up an image into sufficient chunks versus compatibility with older OCI runtimes that may have problems with larger number of layers. However, with recent podman 5 for example with newer overlayfs, it works to use over 200 layers
--reference <REFERENCE>
Tag to use for output image, or `latest` if unset [default: latest]
--output <OUTPUT>
Output image reference, in TRANSPORT:TARGET syntax. For example, `containers-storage:localhost/exampleos` or `oci:/path/to/ocidir`

--version Print version information and exit
-q, --quiet Avoid printing most informational messages
$ rpm-ostree compose image --help
Usage: baseimage [OPTIONS] <MANIFEST> <OUTPUT>
Arguments:
<MANIFEST>
Path to the manifest file
<OUTPUT>
Target path to write
Options:
--cachedir <CACHEDIR>
Directory to use for caching downloaded packages and other data
--source-root <SOURCE_ROOT>
Rootfs to use for resolving package system configuration, such as the yum repository configuration, releasever, etc
--authfile <AUTHFILE>
Container authentication file
--layer-repo <LAYER_REPO>
OSTree repository to use for `ostree-layers` and `ostree-override-layers`
-i, --initialize
Do not query previous image in target location; use this for the first build
--initialize-mode <INITIALIZE_MODE>
Control conditions under which the image is written
[default: query]
Possible values:
- query: Require the image to already exist. For backwards compatibility reasons, this is the default
- always: Always overwrite the target image, even if it already exists and there were no changes
- never: Error out if the target image does not already exist
- if-not-exists: Initialize if the target image does not already exist
--format <FORMAT>
[default: ociarchive]
[possible values: ociarchive, oci, registry]
--force-nocache
Force a build
--offline
Operate only on cached data, do not access network repositories
--write-lockfile-to <WRITE_LOCKFILE_TO>
Path to write a JSON-formatted lockfile
--lockfile <LOCKFILES>
JSON-formatted lockfile; can be specified multiple times
--lockfile-strict
With --lockfile, only allow installing locked packages
-l, --label <label>
Additional labels for the container image, in KEY=VALUE format
--image-config <IMAGE_CONFIG>
Path to container image configuration in JSON format. This is the `config` field of https://github.com/opencontainers/image-spec/blob/main/config.md
--touch-if-changed <TOUCH_IF_CHANGED>
Update the timestamp or create this file on changes
--copy-retry-times <COPY_RETRY_TIMES>
Number of times to retry copying an image to remote destination (e.g. registry)
--max-layers <MAX_LAYERS>
Maximum number of layers to use. The default value of 64 is chosen to balance splitting up an image into sufficient chunks versus compatibility with older OCI runtimes that may have problems with larger number of layers. However, with recent podman 5 for example with newer overlayfs, it works to use over 200 layers
-h, --help
Print help (see a summary with '-h')
