I installed a very minimal set of packages (<400) on a Fedora 8 system
(no graphical interface at all, meant for bare-bones FTP and Apache service)
and found it necessary to turn off SELinux by putting "selinux=0" in the
kernel args in grub.conf to allow *any* account to login to a text console.

A sample of the SELinux/audit message in syslog file:
   Feb 22 09:29:06 testhost kernel: audit(1203701346.285:4): avc:  denied
     { entrypoint } for  pid=2136 comm="login" path="/bin/bash" dev=dm-0
     ino=1736707 scontext=system_u:system_r:hotplug_t:s0-s0:c0.c1023
     tcontext=system_u:object_r:file_t:s0 tclass=file

"login" isn't allowed to access "/bin/bash"?!?

I probably need to take this one to another [SELinux] forum, eh?
Not really keen on disabling SELinux for a box that will eventually
sit on the Internet.  :drunk:
