- New service that starts again an OCI application that stopped on its own, such as Frigate after Save & Restart. A stop or shutdown asked by the user, a backup, a migration and a ProxMenux operation are never undone. - The installer asks it in both modes and proposes what the recipe declares; it is changed from the management menu or with the Watchdog switch of the container modal in the Monitor. - Notifications when the watchdog restarts an application and when it keeps stopping. - The service is recorded in the change journal, and the feature is documented.
