I don't like this approach because if it's a huge repository the user
would have to clone again, not only if he was using v1.8.3, but also
if he was using the latest and greatest (because you are changing the
location again). It's relatively trivial to move from the old to the
shared organization, so that's what I vote for. Besides, I don't see
the point of having a '.shared/.hg' directory, and nothing else on
that '.shared' folder.
So, here's my patch. If only Junio read them.
Subject: [PATCH] remote-hg: add shared repo upgrade
6796d49 (remote-hg: use a shared repository store) introduced a bug by
making the shared repository '.git/hg', which is already used before
that patch, so clones that happened before that patch, fail after that
patch, because there's no shared Mercurial repo.
It's trivial to upgrade to the new organization by copying the Mercurial
repo from one of the remotes (e.g. 'origin'), so let's do so.
