Be careful to double check what you are testing: in your situation it's
not clear whether /sbin/reboot is a symlink to systemctl (part of
systemd, so I would expect this not to work if you were not running
systemd as the init system) or a separate binary.
Jonathan, I started thinking about lost work where someone restarted
the computer while I was away from it and thought what if you can
lock-screen and lock access to console at the same time. Is that
something that could be done? Helpful?
I know someone can pull the cord or press the power button, I got past that.
I use vlock -a in a VC to lock all the consoles. I've been using
it for years so I hadn't noticed the -n switch that allows you to
run it in X (with switching to a VC first).
You can still ssh into, and scp to, the machine while it's locked.
AFAICT Debian's versions allow unlocking with the root password as
well as the user's, which is handy if you forget which username
you were logged in under when you vlock'd it.
