EXPERIMENTAL WARNINGS:
- Add prominent warnings that bootc on Debian is HIGHLY EXPERIMENTAL
- Clarify that NO reproducible bootc images exist yet
- Warn that everything is still experimental and not production-ready
- Add DO NOT use in production warnings throughout
DEBIAN VERSION CORRECTIONS:
- Use Debian Sid (unstable) for base image building (like Fedora rawhide)
- Correct dangerous claims about 'tested' configurations
- Mark all configurations as experimental, not tested
- Remove false claims about production readiness
SAFETY IMPROVEMENTS:
- Add experimental warnings to all base image documentation
- Clarify that bootc is not stable on Debian yet
- Emphasize testing-only use on virtual machines
- Remove misleading production recommendations
This corrects dangerous misinformation that could lead to
data loss and system instability in production environments.
DEBIAN VERSION UPDATES:
- Debian 12 (Bookworm) is now oldstable with outdated OSTree packages
- Debian 13 (Trixie) is now stable and recommended for bootc
- Debian 14 (Forky) is testing with latest OSTree libraries
- Update all Containerfiles to use debian:trixie-slim
OSTREE COMPATIBILITY:
- Document OSTree version requirements for each Debian release
- Add backporting guide for newer OSTree libraries from Forky to Trixie
- Explain benefits of newer OSTree (bootupd support, better bootc compatibility)
- Update compatibility matrix with current Debian status
RECOMMENDATIONS:
- Recommend Debian 13 (Trixie) as minimum for production use
- Suggest Debian 14 (Forky) for latest OSTree libraries
- Provide backporting instructions for Trixie users
- Update testing matrix to reflect current Debian releases
This addresses the critical issue that Debian 12's OSTree packages
are too old for modern bootc/bootupd requirements.
- Remove ./bootc/ from .gitignore since bootc is now a git submodule
- Add standard ignore patterns for temporary files, editor files, OS files
- Add note explaining that bootc/ is a submodule, not ignored
