 Quine distro of Linux based on uBlue Aurora
 
-## systemd/user/disk-cleanup.{service,timer}
+## Building
 
-Weekly, runs as the user, no privilege needed: `podman system prune -af`,
-`flatpak uninstall --unused -y`, clears `~/.cache`.
+`Containerfile` builds a custom bootc image on top of `ghcr.io/ublue-os/aurora:stable`,
+layering in everything under `overlay/`:
 
 ```sh
-cp systemd/user/disk-cleanup.* ~/.config/systemd/user/
-systemctl --user daemon-reload
-systemctl --user enable --now disk-cleanup.timer
+podman build -t quine-linux -f Containerfile .
 ```
 
-## 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).
-
-```sh
-sudo cp systemd/system/rpm-ostree-cleanup.* /etc/systemd/system/
-sudo systemctl daemon-reload
-sudo systemctl enable --now rpm-ostree-cleanup.timer
-```
+An ISO can then be generated from the built image with `bootc-image-builder`.
 
 ## overlay/
 
-Files here mirror their path on the root filesystem, meant to be baked into
-the image (e.g. `COPY overlay/ /` in a future Containerfile). Until then,
-apply manually:

+- `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`.
 
-## systemd/journald.conf.d/size-cap.conf
+### 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.
 
-```sh
-sudo mkdir -p /etc/systemd/journald.conf.d
-sudo cp systemd/journald.conf.d/size-cap.conf /etc/systemd/journald.conf.d/

+### 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.
