Well, I think it was just that give-all-users-of-your-system-full-root-access
thing called `chmod 4777' (which means suid root + world writable) ..... but
I'd also call setting /sbin/halt and /sbin/reboot mode 4755 a bad idea since
they take -f and -n parameters to do the shutdown/reboot without syncing.

You should better use something like sudo or ctrl-alt-del on the console.
