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.
