  # {Rugged::Repository.clone_at} doesn't support :alternates, which
  # completely breaks how thin repositories need to work. To circumvent
  # this we manually create a Git repository, set up git remotes, and
  # update 'objects/info/alternates' with the path. We don't actually
  # fetch any objects because we don't need them, and we don't actually
  # use any refs in this repository so we skip all those steps.
