# Debian Forge: Realistic Development Roadmap

## Project Overview
Debian Forge is a Debian atomic build system that combines:
- **OSBuild architecture** (forked and modified for Debian)
- **debos logic** (for Debian package management)
- **Koji-like orchestration** (for build management)

## Development Phases

#### Week 1-2: Project Setup
- Set up development environment
- Fork OSBuild repository
- Download and analyze debos source code
- Set up basic project structure

#### Week 3-4: Code Analysis
- Analyze OSBuild architecture and identify Fedora-specific components
- Map debos functionality to OSBuild components
- Identify integration points between OSBuild and Koji-like functionality
- Document current architecture and planned changes

#### Week 5-6: Planning and Design
- Design Debian-specific component architecture
- Plan Koji-like orchestration system
- Define interfaces between components
- Create detailed technical specifications

**Deliverables**: Project structure, architecture documentation, technical specifications

### Phase 2: Core OSBuild Modification (Weeks 7-18)

#### Week 7-10: Package Management Layer
- Replace RPM package management with Debian package management
- Integrate debos package handling logic
- Implement Debian repository handling
- Test basic package operations

#### Week 11-14: Build Environment Integration
- Replace Mock integration with sbuild/pbuilder integration
- Implement Debian build environment setup
- Test build environment creation and management
- Validate package building in Debian environments

#### Week 15-18: OSTree Composition
- Adapt OSTree composition for Debian packages
- Test OSTree commit creation from Debian packages
- Validate filesystem composition
- Test basic atomic functionality

**Deliverables**: Modified OSBuild with Debian package support, working OSTree composition

### Phase 3: Build Orchestration (Weeks 19-30)

#### Week 19-22: Basic Orchestration
- Implement build scheduling system
- Add build queue management
- Implement basic resource allocation
- Test build submission and tracking

#### Week 23-26: Build Management
- Add build status tracking
- Implement build logging and monitoring
- Add build history and artifact management
- Test complete build lifecycle

#### Week 27-30: Environment Management
- Implement isolated build environment management
- Add build host monitoring and health checks
- Implement build environment cleanup
- Test environment isolation and management

**Deliverables**: Working build orchestration system, build environment management

### Phase 4: Integration and Testing (Weeks 31-42)

#### Week 31-34: System Integration
- Integrate modified OSBuild with orchestration system
- Test complete build pipeline from submission to completion
- Validate multi-stage build workflows
- Test error handling and recovery

#### Week 35-38: Output Generation
- Test image generation (ISO, QCOW2, RAW)
- Validate bootc container creation
- Test multi-format output generation
- Validate image bootability

#### Week 39-42: Performance and Stability
- Performance testing and optimization
- Stress testing with multiple concurrent builds
- Bug fixing and stability improvements
- Documentation updates

**Deliverables**: Integrated system, working image generation, performance optimization

### Phase 5: Web Interface and Production Features (Weeks 43-54)

#### Week 43-46: Basic Web UI
- Implement basic web interface for build management
- Add build status monitoring
- Implement build submission forms
- Test web interface functionality

#### Week 47-50: Advanced Web Features
- Add build history and search
- Implement user management and permissions
- Add system administration interface
- Test complete web interface

#### Week 51-54: Production Readiness
- Security testing and hardening
- Performance optimization for production loads
- Documentation completion
- Deployment preparation

**Deliverables**: Web interface, production-ready system, complete documentation

## Resource Requirements

### Development Team
- **1 Senior Developer**: OSBuild modification and integration
- **1 Developer**: Build orchestration and Koji-like functionality
- **1 Developer**: Web interface and user experience
- **1 DevOps Engineer**: Build environment and deployment

### Infrastructure
- **Development Environment**: Debian-based development machines
- **Build Hosts**: Multiple build environments for testing
- **Testing Infrastructure**: Virtual machines for image testing
- **CI/CD Pipeline**: Automated testing and deployment

### Dependencies
- **OSBuild**: Fork and modify existing codebase
- **debos**: Extract and integrate Debian logic
- **OSTree**: Core atomic functionality
- **bootc**: Container creation and management

## Risk Factors

### Technical Risks
- **OSBuild Complexity**: OSBuild may be more complex than anticipated
- **Integration Challenges**: Combining three different systems may have unexpected issues
- **Performance**: Atomic builds may be slower than traditional builds
- **Compatibility**: Debian packages may have edge cases not handled by debos

### Timeline Risks
- **Scope Creep**: Adding features beyond core functionality
- **Integration Delays**: Unexpected issues when combining systems
- **Testing Complexity**: Atomic systems require more thorough testing
- **Documentation**: Comprehensive documentation takes time

### Resource Risks
- **Developer Availability**: Team members may have other commitments
- **Infrastructure Issues**: Build environment setup may be complex
- **Dependency Changes**: Upstream projects may change significantly

## Success Criteria

### Phase 1 Success
- Complete project setup and analysis
- Clear understanding of integration requirements
- Detailed technical specifications

### Phase 2 Success
- Modified OSBuild with Debian package support
- Working OSTree composition for Debian packages
- Basic atomic functionality validation

### Phase 3 Success
- Working build orchestration system
- Build environment management
- Complete build lifecycle support

### Phase 4 Success
- Integrated system with working build pipeline
- Image generation and bootc container creation
- Performance and stability validation

### Phase 5 Success
- Production-ready system with web interface
- Complete documentation and deployment guide
- Community adoption and feedback

## Timeline Summary

- **Total Duration**: 54 weeks (approximately 13 months)
- **Phase 1**: 6 weeks (Foundation and Analysis)
- **Phase 2**: 12 weeks (Core OSBuild Modification)
- **Phase 3**: 12 weeks (Build Orchestration)
- **Phase 4**: 12 weeks (Integration and Testing)
- **Phase 5**: 12 weeks (Web Interface and Production)

## Next Steps

1. **Immediate**: Set up development environment and fork OSBuild
2. **Week 1-2**: Begin code analysis and architecture planning
3. **Week 3-4**: Complete analysis and start design phase
4. **Week 5-6**: Finalize technical specifications and begin implementation

This roadmap provides a realistic path to a working Debian Forge system while acknowledging the complexity of integrating three different build systems and the time required for thorough testing and validation.
