Is selinux 'disabled' or just non-enforcing?  If it is enabled, but
even non-enforcing, it still won't allow the security attributes to be
set.

   $ selinuxenabled; echo $?

should give '1' if it is truly disabled.  I believe you have to
disable it at startup time, so if you've changed the config file, you
might need to reboot.
