Most all my admin friends (90% of whom are in mixed shops) prefer RHEL for
their Linux needs.  Most are smallish/medium shops; only one clusters.  I
haven't asked flat out, but the reason seems to be thin staffing.  If
they're on vacation/hit by a bus, a couple of other people have a fighting
chance of doing what's needed, with the aid of RH's support.

The rest of the xxNIX use is just smatterings.  One open BSD.  Some legacy
Sun, HP and IBM AIX/Linux.  One Suse, I think.

They generally hand a Kubuntu live DVD to any technoid user/buddy of theirs
who wants to play.  The masses seem to prefer K to Gnome 5 or 10 to one.
