Hmm, I kinda like the fact that the C-A-Del stuff completely bypasses
the console and is handed to us directly from the kernel. I'd thus
prefer if we could stick to it. That said, force-reboot makes a lot of
sense to attach to C-a-d too? Maybe a logic like this:
- press it once, and a clean shutdown is initiated
- press it thrice, and the current job list is displayed, plus a short
hint that pressing it seven times will result in a forced reboot
- press it seven times and we initiate a forced reboot
(Not tied to the 7 times, could be 5, or 10, or whatever...)
Seems kinda natural to me to have this scheme where we as first
emergency step we have useful information, and then as second step we
actually just reset things.
Does this make sense?
