configuration.nix NixOS Install

[Asten-Valentinus]

I have found the nix run github:nixified-ai/flake#invokeai-nvidia install method inadequate, as it disappears after running sudo nix-store --optimise.

I am aware that the standard way to install software on NixOS is to add it to the configuration.nix, and while I've gotten partway through the process, I can't find anywhere that tells how to do this with Nixified-AI.

Can you give advice on how to do this? Thanks in advance.

And sorry if this is obvious to other users, I am starting out with NixOS.

System Info: NixOS 24.05 w/ flakes

flake.nix:

{
  description = "System Flake";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.05";
    nixai.url = "github:nixified-ai/flake/master";
  };

  outputs = { self, nixpkgs, ... }@inputs: {
    nixosConfigurations.nixos = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        ./configuration.nix
      ];
      specialArgs = { inherit inputs; };
    };
  };
}

configuration.nix:

{ lib, config, options, inputs, pkgs, ... }:

{
  ...
  # What do I put here?
  ...
}

Lack of installation and other documentation is long standing issue, see #2 and #26. As of now, to my knowledge, the closet thing and generally the best practice is to use nix build instead, which will build a result folder and pin it to the GC Roots which should prevent it from getting removed.

Thanks! Doing that and testing, it stayed like you said.
Not the neatest solution, but it is way better than nothing!
