The preferred-poweroff property sounds better to me, too. I can see
two ways of doing that though, and I'm not sure which one you mean.
Would you put that as a bool property into the device that does the reboot,
or would you put it as reference into the /chosen or /aliases node?

I think the latter would be better as it avoids any ambiguity, but
either way would work.
