### r1 - 2025-01-27 14:33:00
**Author:** Shift5-Platform-Engineering  
**Message:** (no message)

**Files Modified:**
- Initial customizations for Shift5 Platform Engineering
- Project fork/adaptation from upstream SL-Micro (baseline establishment)

## Summary

This series of revisions represents the customization of the SL-Micro project for Shift5 Platform Engineering use cases. Key changes include:

### File-Specific Modifications

**`SL-Micro.kiwi` (Main KIWI configuration)**
- r5: Experimental switch from GRUB2 to systemd-boot bootloader
- r6: Removed console parameter from systemd-boot configuration
- r7: Reverted back to GRUB2 with original console configuration

**`config.sh` (System configuration script)**
- r4: Disabled ModemManager service (commented out systemctl enable)

**`README.md` (Project documentation)**
- r8: Added comprehensive 179-line documentation file

### Development Pattern Analysis

1. **Bootloader Experimentation** (r5-r7): Three-revision cycle testing systemd-boot
   - Initial implementation → parameter refinement → reversion to original
2. **Network Management** (r4): Deliberate removal of ModemManager for custom networking
3. **Documentation** (r8): Late-stage addition of comprehensive project documentation
4. **Foundation** (r1-r3): Initial customizations with unspecified changes

### Technical Impact

- **Boot Process**: Final configuration uses GRUB2 with `console="gfxterm"`
- **Network Stack**: ModemManager disabled, relying on NetworkManager only
- **Documentation**: Comprehensive coverage of build system and architecture

## Notes

- Revisions 1, 2, and 3 lack detailed commit messages but represent foundational changes
- Revisions 5-7 show an iterative approach to bootloader configuration
- Revision 8 adds important project documentation for future maintainers
