I think that the standard practice with the existing toolset is to
clone with reference and then repack. That is:
$ git clone --reference <borrowee> git://over/there mine
$ cd mine
$ git repack -a -d
And then you can try this:
$ mv .git/objects/info/alternates .git/objects/info/alternates.disabled
$ git fsck
to make sure that you are no longer borrowing anything from the
borrowee. Once you are satisfied, you can remove the saved-away
alternates.disabled file.
