Hi Jason,

Just filing the bug and I realise I did not save any AVCs relating to 
dhcpc_script_t, but only those for resolvconf itself. It would be useful 
to include the former but to do that I need to unwind my locally patched 
policy. I know I can use semodule -r to remove the patched module, but 
how do I get the original policy re-instated given it is part of the 
core? I guess I could create another local module from my git clone and 
load that?

Thanks,

Robert
