The series looks okay to me. I expect Augie will decide on taking this or not.

The make way would be to depend on real files, but I don't care much about it
since our Makefile is full of phony rules.

contrib/docker/ubuntu-%: contrib/docker/ubuntu.template
	sed "s/__CODENAME__/$*/" $< > $@

docker-ubuntu-trusty: contrib/docker/ubuntu-trusty
	contrib/dockerdeb ubuntu trusty
