Merged.
The ipsec stuff definitely needs some more work.
I have attached is an ipsec.te file that uses daemon_domain for both the
ipsec and ipsec_mgmt stuff, removes the rules covered by daemon_domain,
removes all the comments so all of the allow rules can easily be seen,
and groups the allow rules.
Now, what can be eliminated?
Petre posted on Oct 25th racoon te and fc files. Maybe we should split
out the key management stuff.
Any thoughts?
