Thank you for clarifying and explaining :) I mixed things up a bit. Guix doesn't have a stable channel but Nix does. Twice a year sounds quite fast - but maybe that's just what I'm used to from Ubuntu LTS. I can't imagine being a package maintainer and having to deal with build issues that often (I guess it only targets x64 so it's not too bad) > If you really need that kind of stability I guess I don't really 'need' it .. but I just rather my system not be constantly updating and changing under me. Looks like you have run stable and add unstable packages as needed: https://discourse.nixos.org/t/installing-only-a-single-package-from-unstable/5598/9 https://discourse.nixos.org/t/installing-only-a-single-packa... (like running LTS and adding PPAs)
