# apt-ostree Package Merge Summary

## Overview
Successfully merged the separate `apt-ostree` (CLI tool) and `apt-ostreed` (daemon) packages into a single `apt-ostree` package. This simplifies installation, dependency management, and maintenance.

## Changes Made

### 1. **debian/control**
- Removed the separate `apt-ostreed` package
- Updated main `apt-ostree` package description to mention it contains both components
- Added `polkitd` and `dbus` dependencies directly to the main package
- Removed circular dependency between packages

### 2. **debian/rules**
- Modified installation rules to install both binaries into single package directory
- All daemon files (systemd services, polkit policies, config files) now go into main package
- Updated paths from `debian/apt-ostreed/` to `debian/apt-ostree/`

### 3. **debian/apt-ostree.postinst**
- Added daemon service setup functionality (`setup_service`)
- Added directory creation and permission setup (`setup_directories`)
- Added polkit rules reloading (`reload_polkit`)
- Removed dependency check for separate `apt-ostreed` package
- Integrated both CLI and daemon setup logic

### 4. **debian/apt-ostree.postrm**
- Added daemon service cleanup (`cleanup_daemon`)
- Added daemon file cleanup on purge (`cleanup_daemon_files`)
- Integrated both CLI and daemon cleanup logic

### 5. **debian/apt-ostree.prerm**
- Added daemon service stopping before removal
- Added daemon configuration backup functionality
- Enhanced backup to include both CLI and daemon configs

### 6. **debian/apt-ostree.triggers**
- Merged daemon triggers (polkit, systemd, D-Bus) into main package triggers
- Added triggers for `/usr/share/polkit-1/actions`, `/lib/systemd/system`, and `/usr/share/dbus-1/system-services`

### 7. **debian/apt-ostree.conffiles**
- Created new conffiles file for the main package
- Added daemon configuration file as a conffile: `/etc/apt-ostreed/apt-ostreed.conf`

### 8. **Cleaned up old files**
- Removed `debian/apt-ostreed.postinst`
- Removed `debian/apt-ostreed.postrm`
- Removed `debian/apt-ostreed.triggers`
- Removed `debian/apt-ostreed.conffiles`
- Removed `debian/apt-ostreed.substvars`

## Package Contents

The new single `apt-ostree` package now contains:

### CLI Components
- `/usr/bin/apt-ostree` - Main CLI binary
- `/usr/share/man/man1/apt-ostree.1` - Manual page
- `/usr/share/bash-completion/completions/apt-ostree` - Bash completion
- `/usr/share/zsh/vendor-completions/_apt-ostree` - Zsh completion

### Daemon Components
- `/usr/libexec/apt-ostreed` - Daemon binary
- `/lib/systemd/system/apt-ostreed.service` - Systemd service
- `/lib/systemd/system/apt-ostreed.socket` - Systemd socket
- `/usr/share/polkit-1/actions/org.projectatomic.aptostree1.policy` - Polkit policy
- `/etc/apt-ostreed/apt-ostreed.conf` - Daemon configuration

### System Integration
- `/var/log/apt-ostreed` - Log directory
- `/var/cache/apt-ostree` - Cache directory
- `/var/lib/apt-ostree` - State directory

## Dependencies

The single package now has these dependencies:
- `libc6 (>= 2.39)`
- `libgcc-s1 (>= 4.2)`
- `libostree-1-1 (>= 2025.2)`
- `ostree`
- `systemd`
- `libapt-pkg7.0 (>= 3.0.0)`
- `polkitd`
- `dbus`

## Benefits

1. **Simplified Installation**: Users only need to install one package instead of two
2. **Better Dependency Management**: No circular dependencies between packages
3. **Easier Maintenance**: Single package to maintain and update
4. **Consistent Versioning**: Both components always have the same version
5. **Cleaner Uninstallation**: Single command removes all components
6. **Reduced Package Complexity**: Fewer package files and scripts to manage

## Build Results

- **Package Name**: `apt-ostree_0.1.0-2_amd64.deb`
- **Size**: ~1.6 MB (includes both CLI and daemon)
- **Build Status**: ✅ Successful
- **Installation**: Both components install from single package
- **Service Management**: Daemon service automatically configured and started

## Testing

The package has been successfully built and verified to contain:
- ✅ CLI binary (`apt-ostree`)
- ✅ Daemon binary (`apt-ostreed`)
- ✅ Systemd service files
- ✅ Polkit policies
- ✅ Configuration files
- ✅ All necessary directories and permissions

## Future Considerations

1. **Version Management**: Both components will always be updated together
2. **Configuration**: Single package makes configuration management simpler
3. **Rollbacks**: Package rollbacks affect both components simultaneously
4. **Testing**: Integration testing can be simplified with single package
