Sorry, but this is not at all true, though it often seems so. Unlike reboot, shutdown attempts to cleanly stop all processes. Things like databases can be badly damaged by a reboot. Other processes save state when stopped and that is lost with a reboot. Simply stated, doing a reboot as a standard method of restarting a system is not a good idea and that is why it is not owned by the operator group. -- R.
