Is that a question for some sort of a viva-voce?
anyway, the equivalent of 'supervisor' in unix is 'root'. When
logged in as 'root' you can do a lot more damage (like typing "rm
-rf / tmp/*"). But then there need not be just one absolute
supervisor. You can setup multiple supervisors for various
services on your machine (mail, web server, etc.,.) all by just
playing with the permissions and ownerships.
