selinux and NFS?

[Dave Alden <alden math ohio-state edu>]

Hi,
  I'm wondering how selinux is going to interact with non-FC2 machines?  My
mail server and "home" server are both running RedHat 8.0 for now and this
summer I'm planning on taking them to RHEL 3.  My users login to 3 different
systems (Mac OS X, Solaris and RedHat/Fedora linux) and get the same home
directory.  Am I going to have to disable selinux?
...thnx,
