Developer Contact: Debian Atomic Team

📋 Executive Summary

apt-ostree is a critical component for Debian Atomic, serving as the Debian equivalent of Fedora's rpm-ostree. The tool is currently in early development with a solid CLI foundation but limited backend implementation. This report documents the current status, testing results, and development priorities.

  • ✅ Configuration: Creates default config files automatically
  • ✅ Log Rotation: Sets up proper log rotation configuration

🚧 Issues Found

1. Command Implementation Gap

Severity: Medium
Description: Most commands return "Not yet implemented"
Impact: CLI is complete but backend functionality is missing
Status: Expected for development version

2. Package Search Functionality

Severity: Low
Description: search command exists but doesn't actually search packages
Impact: Users can't find available packages
Status: Needs backend implementation

3. System Status Reporting

Severity: Medium
Description: status command doesn't provide system information
Impact: Users can't determine current system state
Status: Critical for basic functionality

🎯 Development Priorities

Phase 1: Core Functionality (High Priority)

  1. Implement status command

    • Show current deployment information
    • Display OSTree repository status
    • Report system mutations

  2. Implement search command

    • Search available packages
    • Filter by package name/description
    • Show package metadata

  3. Implement install command

    • Basic package installation
    • Dependency resolution
    • Transaction management

Phase 2: System Management (Medium Priority)

  1. Implement upgrade command

    • System upgrade functionality
    • Rollback capability
    • Update verification

  2. Implement rollback command

    • Previous deployment restoration
    • Rollback verification
    • Boot management

  3. Implement db commands

    • Package database queries
    • Repository information
    • Metadata access

Phase 3: Advanced Features (Low Priority)

  1. Implement compose commands

    • Tree composition
    • Package group management
    • Custom tree creation

  2. Implement kargs commands

    • Kernel argument management
    • Boot parameter modification
    • Persistent changes

🔧 Technical Recommendations

1. Backend Architecture

  • Implement proper transaction management system
  • Add package dependency resolution engine
  • Create OSTree integration layer
  • Implement rollback and recovery mechanisms

2. Error Handling

  • Add comprehensive error messages
  • Implement proper exit codes
  • Add logging and debugging capabilities
  • Create user-friendly error reporting

3. Testing Infrastructure

  • Add unit tests for each command
  • Implement integration tests
  • Create automated testing framework
  • Add performance benchmarking

4. Documentation

  • Add man pages for each command
  • Create user guide with examples
  • Document configuration options
  • Add troubleshooting guide
