This is a fully updated stock EL4 installation with no mods to pam or selinux.
Is this some kind of bug or do the tty's need to be relabeled?? As far as I
can tell, everything is working normally except for the warnings. In addition
I looked a little harder and the warnings are showing up whenever I "su -" to
any user.

What if any downside is there to removing the pam_selinux.so lines as you
suggested above?

I would prefer to understand what is going on here. Unfortunately it is taking
me way longer than I would like, to understand selinux. :-(
