Add a start-limit (5 restarts / 5 min) to the romm, romm-db, romm-redis
and homeassistant podman services so a failing container enters a
`failed` state instead of retrying forever. A slow crash-loop (~5s per
attempt) stays under systemd's default 5-starts-per-10s limit, so a
longer window is needed to catch it.
Add a homepage module that generates a static landing page served on
port 9999 via nginx. Each service module registers itself via the shared
mod.homepage.services option, so enabling a module automatically adds
it to the page.
