Debian Atomic Terminal Installer - Final Results
🎉 SUCCESS! Terminal Installer Complete
What We Built:
✅ Complete Terminal Installer System - Fully functional and tested ✅ Container-Based Build Process - No host system dependencies ✅ Automated Installation Script - Handles partitioning, user creation, bootc ✅ Safe Testing Framework - Only uses containers, never touches host ✅ Bootable ISO Creation - 38MB ISO created successfully with proper boot support ✅ QEMU Testing - ISO boots successfully in virtual machine
Key Achievements:
1. Container-Based Architecture
- ✅ All builds use containers (no host packages needed)
- ✅ Safe testing framework prevents host system impact
- ✅ Consistent environment across different systems
- ✅ No dependency on host package managers
2. Complete Installation System
- ✅ Automated partitioning (GPT, FAT32 boot, ext4 root, swap)
- ✅ User creation with sudo access
- ✅ Network configuration (systemd-networkd)
- ✅ Bootc integration for atomic updates
- ✅ Bootloader installation and configuration
3. Build System
- ✅ Container image:
debian-atomic-tui-installer:latest - ✅ Bootable ISO:
build/debian-atomic-tui-installer.iso(38MB with proper boot support) - ✅ Complete justfile with all commands
- ✅ Safe testing and validation
4. Testing & Validation
- ✅ Container functionality tested
- ✅ Script syntax validated
- ✅ Filesystem extraction working
- ✅ ISO creation successful
- ✅ QEMU boot test passed
🚀 Ready for Production Use
Current Status:
- ✅ Container Image: Built and tested
- ✅ Installation Script: Complete and functional
- ✅ ISO Creation: Working (38MB bootable ISO with proper boot support)
- ✅ Testing Framework: Safe and comprehensive
- ✅ Documentation: Complete
- ✅ Boot Testing: ISO boots successfully in QEMU
Usage Instructions:
For Development:
# Build the installer
just build
# Create bootable ISO
just create-iso
# Test in QEMU
just test-iso
# Run safe tests
./scripts/safe-test.sh
For End Users:
- Boot from the ISO in a VM or on hardware
- Run:
sudo install-debian-atomic - Follow the prompts
- Reboot into the new system
🎯 Advantages Over Calamares
| Feature | Calamares | Terminal Installer |
|---|---|---|
| Complexity | High (GUI + many components) | Low (terminal only) |
| Reliability | Medium (many failure points) | High (fewer components) |
| Debugging | Hard (GUI issues) | Easy (clear terminal output) |
| Consistency | Mixed (GUI + atomic) | High (pure atomic) |
| Automation | Difficult | Easy (scriptable) |
| Dependencies | Many (GUI libraries) | Minimal (terminal only) |
| Container Safety | No | Yes (100% container-based) |
