There should be a restart limit.  If we actually crash starting
opal-prd, then we will get stuck infinitely trying to start it.

This could happen if there are events pending and actually the event
action is crashing prd.  We will keep getting the same attention and
not make any progress.

Does systemd unit file allow a limited restart attempts?
