I thought about going through all "git remote -v" git config --get-regexp '^remote.*.url' is probably more appropriate. Either way, I don't see why such a change should be in the same patch. > This way we wouldn't need to copy by default (bad for big repos), but could still do this > in a cheap way if a slow remote is added later on. > > Btw, is there any reason why we don't just use the local mercurial remotes as shared > repo? Cause it's not under our git dir and might be deleted? Yes. Or moved, or might be in an external drive, or many other reasons.
