@deads2k What about the github.com/openshift/origin/cmd/dockerregistry and github.com/openshift/origin/pkg/cmd/dockerregistry ? They are also part of registry server and should be splitted.

@deads2k I don't know what to do with https://github.com/openshift/origin/blob/master/cmd/dockerregistry/main.go#L20-L23 .

I'm leaning towards doing slightly crazy things and giving you a separate vendor folder, sans cobra. That would let us remove everything else.
