Then I would clone the small repo and work with it. Later I decide I want full history, can I pull from a full repository at that point and get updated? That would need a flag to trigger it since I don't want full history to come over if I am just getting updates from someone else's tree that has a full history. > > Of course, to make up for some of the initial costs, I suspect that some > people who are used to "cvs update" taking 15 minutes to update two files, > it would be a serious relief to see the git kind of "300 objects in five > seconds" kinds of pulls. No more cvs diff taking four minutes to finish. I have to do that every time I want to generate a 10 line patch. Diffs can run locally. No more cvs update to replace files I deleted because I messed up edits in them. And I can have local branches, yeah! What are we going to do about the BEOS developers on Mozilla?
