hibernation unsupported by installer, but is default in gnome

[Chris Murphy]

This combination is sufficiently incongruent to be utterly broken, and
therefore looks a likely blocker in my opinion.

a. It's the default behavior, rather than power off, when battery
power is critical

b. Either systemd or the kernel isn't seeing the hibernation image, or
isn't putting the system into hibernation mode, because it just
reboots when the user hits the power button trying to resume.
Therefore resume doesn't actually happen.

c. The installer doesn't configure systems for hibernation out of the box.

Until b and c are addressed, the simple fix is to address bug a.
