I've been intrigued by nix then guix for several years now, but have yet to give either one a test run. I understand some of the technical differences, but can anyone explain the implications of the license differences to me? I know that NixOS is X11/MIT licensed, and that as a GNU project Guix is AGPL. In practice, if I wanted to use Guix as a base system for hosting a proprietary SaaS website, would there be issues with that? Either way, is there an easier-to-read summary than the license itself anywhere?
