Why are you adding those interfaces, specifically? Shouldn't we be pushing towards 16.04 needs now?

[zyga]

They exist and are trivial to add. I'll check with @jdstrand if there are any ready-made 16,04 specific interfaces that I can do.

[niemeyer]

Again, can we please focus on getting interfaces working at all? It's not very interesting to have more interfaces if none of them work.

AIUI, most everything that we went through in the old-security caps list is supposed to be for 16.04. Last week I converted everything to the new names, moved stuff, removed things, etc. Everything in http://bazaar.launchpad.net/~ubuntu-security/ubuntu-core-security/trunk/files/head:/data/{apparmor,seccomp}/policygroups/ubuntu-core/16.04/* should be moved to 16.04 native interfaces (of which, firewall-control is one of them).
