I occasionally use FETCH_HEAD for such things. If we were to stop writing it automatically, I think the key thing to notice is whether the result was actually stored anywhere else. Or more accurately, whether the user asked for any refspecs on the command line (since we'd still update tracking refs in some cases). If I do: git fetch or: git fetch origin refs/heads/foo:refs/heads/foo then I probably don't care about FETCH_HEAD. But if I do: git fetch origin refs/heads/foo then I'm probably interested in picking the result out of FETCH_HEAD. -Peff
