Excellent, thanks! I've been reading a bit more of http://www.freedesktop.org/software/systemd/man/systemd.service.html
and there are several Restart= options, one of which is "on-failure". That might be better targeted to abnormal endings? I start/stop mythbackend to do mythtv-setup (running that a lot lately)  so I probably don't want to always auto-restart it.

Hika: That's a very tidy way of doing it!
