quine-linux

Quine distro of Linux based on uBlue Aurora

Building

Containerfile builds a custom bootc image on top of ghcr.io/ublue-os/aurora:stable, layering in everything under overlay/:

podman build -t quine-linux -f Containerfile .

An ISO can then be generated from the built image with bootc-image-builder.

overlay/

Files here mirror their path on the root filesystem and are baked into the image via COPY overlay/ / in the Containerfile.

• overlay/etc/... — local/admin config. On the ostree-based image, content shipped here becomes the default /etc and is still locally overridable (3-way merged on upgrade), same as any package-installed /etc file.
• overlay/usr/lib/systemd/... — vendor-shipped units. /usr is replaced wholesale on each image build/upgrade, so anything here always matches the image and isn't meant to be hand-edited on a running system.

overlay/etc/gitconfig

System-wide git config so every user on the box gets main as the default init branch, not master.

overlay/etc/systemd/system/rpm-ostree-cleanup.{service,timer}

Weekly, runs as root via systemd (not cron/sudoers): rpm-ostree cleanup -rb (drops rollback deployment and any pending deployment). Enabled at build time via RUN systemctl enable in the Containerfile.

overlay/etc/systemd/journald.conf.d/size-cap.conf

Continuous 500M journal retention cap instead of a periodic vacuum job.

overlay/usr/lib/systemd/user/disk-cleanup.{service,timer}

Weekly, runs as the user, no privilege needed: podman system prune -af, flatpak uninstall --unused -y, clears ~/.cache. Auto-enabled for every user via overlay/usr/lib/systemd/user-preset/90-quine-linux.preset — no manual systemctl --user enable needed.
