Speaking of initial user setup...it bugs me that I'm forced to create a group.  If I try to pick an existing group, the Fedora installer complains that the group already exists, which is a strange error to report -- no duh it already exists.  (I just want my user account to be part of the "users" group; I don't need my own special group account.)  I always have to delete the group afterwards, then do a system-wide find/chgrp.
