I can think of a few cases where the question is about reboots (reboot tests, post-patch power cycling, remote reboots/power-cycles/restarts).
I can also argue convincingly that in each of those cases you're not really asking about the reboot, but rather all the thing that lead up to it (pre-deployment testing, patching, and remote power control / out-of-band management).

So I agree - this tag can probably go.
