Yes, I can run it multiple times subsequently and it always works. When 
checking the status of nut-[driver|server|monitor] services they all keep 
reporting "active (running)" after waking up from hibernation.

No, I don't have the service created. But I don't mind the UPS killing of 
power - hibernation (=suspend to disk) doesn't require power after all unlike 
suspend to RAM.
