Hmm, I'd prefer if --action= would simply pull the selected actions to the
front instead of just dropping all others? Note that we have to update logind's
CanSuspend() code to look for the other verbs too, and it would be good if we
wouldn't have to make that code configurable too. Hence: Make CanSuspend() (and
friends) simply return true if *any* suspend/freeze/standby verb is available,
but then allow the user via --action to choose which ones is preferredly used.

And yupp, I think making this configurable via copying a unit file sounds good
enough to me. This should be an exotic setting, and not a common one, and hence
a clean but possibly somewhat obscure way to configure this sounds perfect to
me.
