nixos-config VS nix-config

I also took a lot of inspiration from this NixOS config that I think demonstrates a lot of things you can do with them.

Check this repo for reference https://github.com/MatthiasBenaets/nixos-config

The other one I've seen seems more elegant, but I've only seen once and doesn't seem to be fully explain by the author: https://github.com/MatthiasBenaets/nixos-config/blob/master/flake.nix I've tried what he's showcasing here, but it doesn't work the variables are undefined and the tips given by nix-rebuild aren't enough for me to make sense of it.

# nixos-generate-config --root /mnt # git clone https://github.com/matthiasbenaets/nixos-config /mnt/etc/nixos/ (I think this can also be avoided I forgot to check this :| ) # cp /mnt/etc/nixos/hardware-configuration.nix /mnt/etc/nixos/nixos-config/hosts//. # cd /mnt/etc/nixos/ # nixos-install --flake .#

Power user, gvolpe has a great config that heavily customizes nvim.

I forked and customized a fairly advanced Nixos configuration that I can load from a flake on github. (Mine | Original)

I think gvolpe's nix-config repo is what u/ppen9u1n was referencing. Looks like there might be some good ideas to mine there.

I've seen this done with flakes by a NixOS power user named gvolpe. He has it configured to automatically setup each of his different systems with Home Manager, a custom UI, etc. His three different build targets are:

I think NixOS would benefit from easily accessible collection of opinionated modules/profiles/configurations with minimal set of options. Something like gnome-desktop / sway-desktop / etc. Gnome actually does pretty good job here.

The point is: currently my NixOS and Home Manager configurations have over 2k LOC total. When you search for configurations on GitHub/Google you are likely to find complex ones. For example, quick search for "nixos gnome" (Google) gives me link to NixOS Wiki (which describes only Gnome part) and blog post (https://gvolpe.com/blog/gnome3-on-nixos/) which is useful but links to really huge configuration (https://github.com/gvolpe/nix-config) that is overwhelming to any beginner.

Great example of such approach is nixos-hardware (https://github.com/NixOS/nixos-hardware) which provides one-line configuration covering hardware quirks.
