Some kind of automatically geographically selected mirror could be useful.

This came up before on guix-devel [0]. The substitutes are already exposed from the Berlin (CI) machine via the rsync server. The main optimization to do here would be getting rid of the lzip compressed nars, keeping only the zstd variant to roughly reduce space usage for mirrors by half.

I think CI is better geared up for simple rsync right now; QA requires a dedicated Guix System or at least a Guile-authored service, so would be a bit more involved than installing rsync. -- Thanks, Maxim
