On: NixOS is a good server OS, except when it isn't

IIRC guix started off by being compatible with nix package derivations, but they broken it (i also may remember incorrectly).

If nothing changed, they also have a strong ideological drive and funny support any non-free software.

What is a "package derivation"? Packages and derivations are two different things in Guix.

Also, Guix supports proprietary software just fine. It's just not in the main official repo. But there are other repos that have it, e.g. nonguix.
