Description of problem: After changing the selinux "type" (e.g., targeted -> strict), you need to do "touch /.autorelabel" and then reboot. Add code to system-config-securitylevel to do the "touch" automatically. You need to do the relabel when rebooting to "fix everything" for the new policy definitions.
What version of system-config-securitylevel? It's working fine for me under 1.5.7-1.
