Uh… is the NixOS documentation “one of the best around” or have you never checked it? It really can’t be both.
Understand, I’m not trying to criticize NixOS. I use NixOS exclusively and it’s my daily driver. But the documentation really isn’t all there, and it’s not centralized. The best solutions you find across forums, blog posts, random wikis, and by checking other people’s configs like you said.
But yes, the fact you can test things without fear of breaking your system allows you to make hundreds of mistakes stress-free. That’s one of the best features about NixOS.


That’s a round about way of saying RTFM, but even less welcoming. Probably not the kind of thing anyone should be told…
