I daily drive GNU Guix instead, and I would strongly recommend any emacs and/or lisp enthusiasts interested in the benefits of functional, reproducible, declarative, and hackable system management to give it a try!
Do you run the gnu guix distro or just use the package manager? Because iirc it uses only free software, even for drivers. So I imagine it is not that easy to find compatible hardware.
I run the complete system. It's true that the standard iso comes with the linux-libre kernel and the standard channel (think repo) contains only free software. However there is the nonguix channel which comes with the full linux kernel, and all the proprietary drivers you could ask for.
Nonguix offer an iso with the full kernel too in case you have a proprietary wifi card and don't have ethernet for the initial setup. The nonguix README I think is pretty clear, but Systemcrafters also made an excellent guide for doing this.
My wifi card unfortunately requires proprietary drivers and I have personally never had an issue with guix + nonguix for all my software needs, proprietary and otherwise.
yeah, Guix is great. I tried to use NixOS for a while but I couldn't get over how much I dislike Nix as a language. Scheme is way way better imo. Guix definitely isn't as polished Nix given its lower number of users but it's still a very pleasant experience.
