I was assuming a triangular workflow, where your publishing point (that
other people will fetch from) does not know anything about the upstream.
$ git clone git://git.kernel.org/pub/scm/git/git.git
$ hack hack hack; commit commit commit
$ git remote add me myserver:/var/git/git.git
$ git push me
$ git advertise-upstream origin me
If your publishing point is already fetching from another upstream, then
yeah, I'd agree that dynamically generating it from the config is fine.

Yes. The pkt-line versus refs distinction is purely a protocol issue.
You can do anything you want on the backend with either of them,
including faking the ref (you can also accept fake pushes to
refs/mirror, too, if you really want people to be able to upload that
But it is worth considering what implementation difficulties we would
run across in either case. Producing a fake refs/mirror blob that
responds like a normal ref is more work than just dumping the lines. If
we're always just going to generate it dynamically anyway, then we can
save ourselves some effort.
