Thanks for that. The gitosis approach of a single shared unix account (typically `git`) with git-shell and a master authorized_keys file definitely seems simple

Thanks for that. The gitosis approach of a single shared unix account (typically `git`) with git-shell and a master authorized_keys file definitely seems simpler. You lose some of the auditing and security benefits of the one-unix-account-per-human approach, but that might be fine for some use cases.
