What about current instances - can we/do we want to update certmonger
tracking so that their instances are restarted as well?

Anyway, I found few issues SELinux issues with the patch:

1) # rpm -Uvh freeipa-*

certmonger_unconfined_exec_t type was unknown with my selinux policy:

selinux-policy-3.10.0-80.fc16.noarch
selinux-policy-targeted-3.10.0-80.fc16.noarch

If we need a higher SELinux version, we should bump the required package
version spec file.


2) Change of SELinux context with /usr/bin/chcon is temporary until
restorecon or system relabel occurs. I think we should make it
persistent and enforce this type in our SELinux policy and rather call
restorecon instead of chcon
