I can't find a way to restrict prefecting done by scheduled git-maintenance runs to just some remotes and not all of them. I'd like to do it because I have many remotes that are only used occasionally and may be not available at all (e.g. one refers to a testing machine which is often offline) and getting errors like
systemd[nnn]: Failed to start [email protected] - Optimize Git repositories data.
in the journal is annoying.
Is there something I'm missing or is it really not implement and you have to prefetch all or nothing?
