No, it isn't. You can have both local branches and remote branches removed from the cloned bare repo while your --shared clone still uses objects that are no longer retained in the first clone. > It can still be a net win for throw-away clones needed during a build. Basically the only sensible use is for temporary clones used (and deleted again) within a script. -- David Kastrup
