Here’s another idea: allowing ‘guix copy’ to talk to a “raw” remote store—i.e., just /gnu/store + /var/guix/db accessed over SSH. Just like we have (guix store ssh), we could implement raw store operations over SSH using ‘remote-eval’ and (guix store database). Hmm that amounts to implementing a subset of the daemon. Ludo’.
