Looks like new functionality.

Cockpit should really carry its own policy package similar to docker.

Yes, we are treating SELinux as any other dependency. First we get the API and changes we need from the lower level, before implementing the functionality in Cockpit.

Commented on that pull request.

Even though using our own SELinux policy was a great way to get started ... it just started being problematic:

 1. Conflicts between the Cockpit SELinux policy and changes in the various
    Fedoras, mean that we would have had to carry a different SELinux policy
    for each targetted OS.

 2. Our testing used our custom SELinux policy and since users weren't installing
    it this led to false negatives, errors were hidden, and that's bad.

We will create a document/blog where we want to talk about experiences and about advices how to do it or not.

With new userspace (Fedora23+) there is no problem to ship a policy with the same name because we have priorities here. The problems come up with RHEL7 and old Fedoras.

I am more concerned about RHEL then Fedora, since Fedora can have regular updates of selinux-policy it should not be a problem.  RHEL however will lag up to 6 months for an update.
