The question is: why *repeatedly* though? i.e. why does it keep doing
that if nothing else happens? journald should not trigger that all the
time...

Also, there's actually a safety condition in place, the start limit
logic: after a service has been attempted to be started too often
within a time window we refuse starting it again...

So I am a bit puzzled about this. Some logs would be great to have
about this...
