+Notice that, if I manually change the permsissions of `unused`, `badunused` and `tmpunused` to `660`, then other another user of the group can do `git annex unused` and `git annex dropunused 1` without errors. Unfortunately, after `git annex unused`, the ownership of `unused`, `badunused` and `tmpunused` changes from the initial user to the new user, and permissions are reset to `600`, which re-creates the initial problem.
