Ah I thought it was all one file, and maybe that would just be like, commenting out the system section or something.
But I do mean, which apps are installed, what desktop environment, really the user interface, the end user experience that's what I was wondering.
So is there such a repository or not ? Is every nixos user making the configuration file from scratch in vim ?
I figured there should be a repository where most user just pick a ready made file and that's the end of that. Not really having to learn the syntax of that file and writing it down ?
