I maintain multiple copies of the same repo because I keep each one checked

--reference, we could also use git fetch --reference to reference a local
repo when doing a fetch to pull in updates.

I think it is just spelled:

   echo $reference_repo >>.git/objects/info/alternates
   git fetch

We need "--reference" with clone because that first line needs to happen
after clone runs "git init" but before it runs "git fetch". And if you
cloned with --reference, of course, the alternates file remains and
further fetches will automatically use it.

Aha, thanks, hadn't realized that. Just checked and yes, the alternates file is already set in all of these different copies.
