It was not loaded because the load_policy in FC5 looks at
your /etc/selinux/config to determine what policy to load.  It does not
use the command line parameter, which is what the message is saying.
The refpolicy makefile provides this parameter for compatibility for
older SELinux machines.  What happened is that you loaded the policy
configured set in /etc/selinux/config.

Second, you are using a monolithic policy build configuration, which is
not supported in FC5.

Yes.  The "policy from config file" is the policy that was loaded.

You were relabeling using the file contexts from your custom refpolicy,
but the FC5 policy was loaded, and it turns out that the configurations
differ; therefore, there are invalid contexts.
