Normally that is suppressed because default_canoncon checks whether
security_canonicalize_context() returned with errno ENOENT
(i.e. /selinux/context didn't exist, as with SELinux disabled or in a
chroot).  But the patch from Ian Kent for !selinux_mnt changes that
behavior unless those checks also set errno to ENOENT, which I added
upstream, but is _not_ in your FC5 backport.
