How is Guix? I run NixOS right now, and I didn't find Guix until like right after I invested all the time and effort to learn Nix. I kind of want to switch, but I also don't really want to abandon Nix right after I learned it.
The main difference with NixOS is that it's fully free. Another difference is that the language used for configuration in Guix is Scheme, a general purpose functional language.
Not much else different? That's kinda what I expected, about the same experience, just in Guile Scheme instead of Nix and with a different package repo.
