Definitely looking to minimize breakage here, and it sounds like it'll be to the point of "none", or this won't fly. I think this may require having "legacy" aliases for certain interfaces and the like, to both provide a less problematic interface name as the new default, but prevent breaking any existing setups. -- Jarod Wilson ja...@redhat.com
