Yeah, something like that works. Please notice, however, that what I usually do is: $ git remote update torvalds $ git merge <tag> (or git pull . <tag>) So, for the above to work, it should store somehow the remote from where a tag came from. The reason is that I keep locally a cache with several tree clones (in bare mode) s that I bother enough to cache (linus, -stable, -next), as pulling from BR is time consuming, and I want to do it only once and use the same "cache" for all my git clones. I have a few git workdirs for my upstream work, but, as a patch developer, I also have "independent"[1] git repositories. [1] Due to disk constraints, the clones actually use --shared. So, the common objects are actually stored inside a single tree. Thanks, Mauro
