OOOOOH! We have a bingo:

Makes sense ... now :-/ Since diskfarm is a "server" and gezebel is a desktop and neither ever gets shut down to pause, we don't need to go there.
Arguably, hibernation can be used instead of poweroff triggered by a power failure (UPS monitoring daemon). -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)
