Dubious Ownership in git-http-backend

Over the last week I've been working on replacing imladris, the server that does most of handwaving gesture this. I first installed the ur-imladris on November 5th, 2011 from a Debian 6.0 (squeeze) iso into a KVM 0.12.5 VM. That system kept being upgraded all the way to Debian 12.0 (bookworm) and probably could have continued but it was time. There have been a number of decisions over the years and it was time to re-evaluate some of them. A complete re-install also means I can find all the things I've forgotten to update in Puppet (it was many, oh so many) and get those buttoned back up. Every release I re-install my name servers (they do DNS and LDAP) so I know they work well but imladris is a much more complex beast. Anyway, this isn't so much asbout that as it is about chasing down some behavior in the git-http-backend process that surprised me. I host all my git repositories using a combination of the native git smart-http stuff (that's git-http-backend), gitweb, and gitolite.…
