I can appreciate how holistic the GNU ecosystem seems to be. I'm a lover and user of Nix, so whenever something about Guix comes up, I draw the contrast. In this case, GuixSD is using Shepherd, which uses Guile for configuration and feels like natural continuity within the system. NixOS, on the other hand, provides systemd (and only systemd). In the case of nix, it's smart to leverage existing technologies, for velocity, yes, but also as a sort of proof that the core principles behind nix can apply even over systems and tools that are completely unaware of nix concepts; on the other hand, GNU really makes me a believer in the fact that Guix is very pure.
