Well, my point is those repos are already cached on every worker in
/opt/git (e.g., /opt/git/openstack/nova) and you can git clone, cp
or rsync those into your package build chroot. Then git remote
set-url, update and reset --hard to the branch you want so that
you're just pulling the delta from the last few hours (up to a day's
worth generally, if everything is working correctly). Right now all
our job workers have basically current caches of all ~700 repos
hosted in our Gerrit.
