W.r.t to Bzr's shared repository, this is different in that the sharing is asymmetric: what you pull into "trunk" will also be available (without re-fetching) in ws1 but not vice-versa. Also, this comes with a big "NOTE: this is a possibly dangerous operation" in the manpage, because "trunk" doesn't know about "ws1", so a "git gc" in trunk (explicit or implicit) may remove revisions that are still needed by ws1. Bzr avoided the problem by not providing "gc". > For more glitches, ask Stefan. I think that covers it up. Basically, IIUC, the rule for git-new-workdir is "at most one workdir for a given branch". So if you want a "second workdir" of trunk, make a new branch off of "trunk" and then do a "new-workdir" for that new branch. Stefan
