That's is also because his echoed "0" context is not active yet.  It
requires a reboot every time I have done it.  But the other way around
it does not.

No matter how hard you try in a default EL4 or 5 instance you will never
get logged into an apache account.  Root or Not...  Unless you change
the login shell..or exploit it...

apache = /sbin/nologin
postgres = /sbin/bash

Jason,

Nasty things happen when you build rpms like that.  
See www.owlriver.com , Russ has an article there about it [1].
