Btw, why is remote caching with substituter so iffy with NixOS? I encountered the same issues demonstrated in the video. It’s not obvious why an offline substituter should block a local rebuild unless there is some nix option denoting as optional or required. Or why some matching entries in the remote nix-serve store are ignored (or untrusted?)
