Log of systemd with no restart after failure

When a simple service experiences a watchdog failure due to lock-up, stop is never called on the service. The service is transitioned to the "failed" state, but no further action is taken.

If "Restart: on-failure" is set, multiple instances of service will be started because the previously failed instances are not stopped.

I've attached a simple test application that just pets the watchdog a few times and then stops. The attached log shows the resulting behavior for both the default case and the "restart: on-failure" case.

Tested with a user instance of systemd v44 on F17.

This should be fixed in git now. Closing.
