I'd actually forgotten about ctrl-alt-f1+ctrl-alt-del
...must be getting old.

Not that I want to do so, but can ctrl-alt-f1+ctrl-alt-del be disabled by
the sysadmin?

For "halt," there are always magic keys, as long as that's not disabled by
the sysadmin...

Alt-SysRq reisuo

I definitely like the idea that this is enabled by default in Devuan. I
actually use it quite a lot.
