The idle watchdog terminates the process with os._exit(0). systemd's Restart=on-failure does not restart a unit that exits 0, so a server installed from this template stops for good after the idle timeout rather than restarting. Switch the unit to Restart=always and disable the watchdog in the server env template, since a dedicated always-on server is not the per-session case the watchdog was added for.
