User IDs confuse me.


OK, so root has a user ID of 0. When you add a user, it's given an ID of 500++ (in redhat at least). Other system accounts have lower IDs. That's as much as I know.

Can two users have the same ID #?

Can an ID # be changed for an existing user account?

Does assigning an ID of 0 to a user automatically make them root?

Is there a primer somewhere about user IDs?

Usually I can find out about a topic via this site or google, but I'm at a loss what to search for in this case...

q1: no the ID has to be unique.
q2: yes it can be changed as long as it's unique
q3: to be honest I dont know. One root on a system is more
then enough.
q4: erm.. I dunno
