Guix is based on NixOS. Both are package management systems which, oh by the way, also purport to be Linux distros. I find this very interesting, because I have always grouped Linux distros by which package management system they use. I like Fedora, Mageia, Mandriva, PCLinuxOS and the like because they use my favorite, RPMs. Ubuntu, Mint, and Debian are in the DEB camp. And a few, like Arch, have their own. So here comes some projects that are package management first and then also distributions. I like the concept. But they seem to have fooled DistroWatch, because neither one is listed. Has anyone used either one?
