Yes, we'll need to make some sort of "reboot requested" flag, and
lifecycle around that.

Out of curiousity, at the app level, what would drive a reboot? I can
see how a kernel or shared library (from the core) might need a reboot,
but what app would require a reboot?

Your gadget snap should be able to specify required snaps on the device.
Other snaps can't have dependencies other than frameworks.
