Yeah, I can use audit2allow. The trouble is that I don't know the
ramifications of just adding that policy on an ad hoc basis - it might
open it up for a real attack.

Plus, of course, selinux does *not* always tell you the truth... meaning,
its error handling is *not* correct. I've posted several times here, and
over in the selinux-fedora group, because we're stuck with CA's
SiteMinder, and selinux would stop it from writing to its own logfile
(apparently because the idiots at CA have the file opened for modify,
rather than append)... but if I run the sealert for that, it claims I only
need to set httpd_unified on, and that does NOT fix it.
