File contexts and how are files labeled?

[Timothy Renner]

First off, thanks for the answers about finding out the SELinux 
transactions...  autrace was the way to go....    Now I have a more 
fundamental problem...  In the file context labels, there are two rules 
that conflict:

/sbin/.*       all files   system_u:object_r:bin_t:s0

       and

/sbin/mount.mymounter   regular file   system_u:object_r:myfile_exec_t:s0

The problem though is that the file gets labeled under the blanket 
/sbin/.* context, rather than the more specific one:

 > ls -lZ /sbin/mount.mymounter
lrwxrwxrwx  root root system_u:object_r:bin_t          
/sbin/mount.mymounter -> /myproject/sbin/mymounter

Any thoughts on this?  Can someone explain how the file context is 
derived from the rules?  Is it as simple as whichever matches first?  
And does anyone know a way around this labeling problem, assuming I 
cannot remove the /sbin/.* rule, but can only add rules through a policy 
module.

Thanks again,
-Tim
