Description of problem:
It was my understanding that by default SELinux is not active
in FC2T3. With an installation of the last one from scratch,
and no change in SELinux defaults, after I tried to add some rpm
updates I got a long series of messages like that:
kernel: security_context_to_sid: called before initial load_policy on
unknown context system_u:object_r:default_t
Over 1500 of these with varying contexts. Only booting with
'selinux=0' as a boot parameter seems to kill that noise.
This is because rpm's check for selinux being enabled or not wasn't
quite good enough, but with new SysVinit, that should be better.
