What did you have in mind? One thing we discussed long ago was the idea of keeping signatures in the store database, and I think Nix=C2=A02.0 does that. That=E2=80=99s something we could borrow. > Is compatibility with the nix-daemon a goal of the Guix project? I=E2=80=99ve come to the conclusion that it=E2=80=99s not a worthy goal, as= in, it would cost more than it=E2=80=99s worth. guix-daemon is already incompatible with nix-daemon on a few things, such as the =E2=80=9Cbuiltin:download=E2=80=9D = derivation builder. > Can we take inspiration from any of the non-daemon features and use > them in Guix? Definitely. > Conversely, is there anything we can upstream to Nix that they might > find useful? Changes in the daemon are pretty much the only thing we could upstream, and I used to do exactly that. At some point I decided to stop following closely upstream and allow ourselves to change the daemon as we see fit. As a result, you may find that not every change that we make to our nix/ directory is directly applicable to current Nix. I=E2=80=99m also hopeful that we can move to a Guile-based daemon in the fu= ture. Overall, I think Nix and Guix still have a lot to share, probably not in terms of code, but at least in terms of design, features, and ideas. The discussions with Eelco at the Guix Workshop demonstrated that! Ludo=E2=80=99.
