AAAARRRRGHGHGHGHGHGHGHH!!!!!!!!!!!!

Ok, a *whole* new problem, which maybe throws everything else out the window.

Look at their home directories again, but this time do ll -Z
/var/www/whatever. Betcha they're something like unconfined_t, or
default_t, or maybe even not labeled. Check /var/log/messages for sealert
messages. And if you *don't* have any, then you need to see if
setroubleshoot\* is installed. If not, install them (server and plugins),
and make sure auditd is on. Then you'll see complaints. Run what's in
messages, which will be of the form "setroubleshoot: SELinux is preventing
/usr/bin/updatedb from read access on the directory /public/apps/.gem. For
complete SELinux messages. run sealert -l
20085a91-0ea5-4794-a7c8-b6e975c27ed4". Run the sealert, and *maybe* the
message will be helpful. It's sometimes only barely, to me, and I've been
fighting to shut selinux up in the logs for years now.

If you thought *Nix sysadmin was complicated, wait till you begin to look
at selinux (which, btw, was written by the NSA, for real).
