While reboot is dangerous and should really only be used in single user mode or an emergency, I don't understood why operator was not allowed to do it. for those who assume that "reboot" is short for "shutdown -r now", it is not. Reboot does not bother shutting down stuff in rc.d while shutdown does. This can result in shutdown not working, but reboot can leave things like database files in bad shape. -- R.
