git-push to a local directory forces unpack/repack?

If I do git-push ~/somelocaldir it forces a full unpack of the
project, is this expected? I was expecting a harmless copy of the
packs...

At the moment, it means 900MB when I am initializing the public repo.
I haven't found the way to convince it to use rsync. Still running
repack.

cheers,
