I don't like the way submodules work. They are good for independent, fairly static externals but for synchronizing two repositories I think they'll be a pain. There's some unpleasant caveats at http://book.git-scm.com/5_submodules.html plus they are really easy to screw up. SJT> Maybe.

Using git-bzr from http://github.com/kfish/git-bzr, it seems you can only push to a single branch, will that still cause problems? I think the Gnus repository is pretty unlikely to branch with abandon, in any case. If Yidong, Stefan, and others are concerned about ghost revisions, we can simply prepare the Gnus -> Emacs synchronization as a patch and submit it through the usual channels or apply it manually ourselves in isolation within Bazaar. This will probably be the modus operandi at first anyhow. Ted
