Hello everyone, I'm very close to finishing my configuration files for NixOS. I have those working on my nixos installation on my external drive, but before I officially move to nixos I'd like to make sure that I'm not doing something wrong.
Could someone please check my config files? (I only use flakes.nix, configuration.nix, home.nix and hardware.nix and I'd say they aren't much complicated.)
My main concearn is that I probably use the import and modules functions wrong (yet somehow they work?). I've read and watched numerous guides for the last 3 months, but I think I still mess this up๐
. I think following a bunch of different guides and videos added to the confusion a bit. (A recent guide I read made me have doubts about my set up.)
This is the link to my nixos configs:

Hopefully by the end of the next week I'll be posting here about having transitioned to linux/nixos:)
Sample of probably wrong usage of
modules in flakes.nix
outputs = {self, nixpkgs, ... }@inputs: {
nixosConfigurations = {
nixos = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
specialArgs = { inherit inputs; };
modules = [
./hosts/default/configuration.nix
inputs.home-manager.nixosModules.home-manager
{
home-manager.useGlobalPkgs = true;
home-manager.useUserPackages = true;
home-manager.users.bs = import ./hosts/default/home.nix;
home-manager.extraSpecialArgs = { inherit inputs; };
}
# inputs.spicetify-nix.nixosModules.default
Sample of probably wrong usage of
imports in configuration.nix
imports =
[ # Include the results of the hardware scan.
./hardware-configuration.nix
#inputs.home-manager.nixosModules.default
];
(I think I'm not using home manager in configuration.nix, that's why I've commented it out, and I'm importing it directly in flakes.nix.)
I'm not seeing anything wrong in the samples you provided. That's pretty much how my own NixOS configuration looks (except mine's a single monolithic
flake.nixgenerated from Org Roam sources, but... the effect is the same anyway).Yo, thanks for this, I was a bit anxious that I might had been starting really wrong.๐ ๐
May I ask a few more things (either directed to you or whoever wants to reply):
inputsargument in both specialArgs and extraSpecialArgs to be used inconfiguration.nixandhome.nix. Do I make use of this argument inside those 2 files?configuration.nixandhome.nixI start with{ config, pkgs, inputs, ... }:arguments. Should I do that? Should I remove/add anything? I suppose this usesconfig,pkgsandinputsfromflakes.nix, making thespecialArgs = { inherit inputs; };andhome-manager.extraSpecialArgs = { inherit inputs; };in flakes.nix unecessary??this sample in
flakes.nixthis sample in
flakes.nix??inputsofflakes.nixto any module that usesspecialArgs(like theconfiguration.nixmodule) andextraSpecialArgs(like thehome-managermodule). Is this correct?Thanks for replying btw, it was a good confidence boost:)
You don't seem to actually use
inputsin yourhome.nixfile so in principle you should be able to remove theline. Doesn't hurt to keep it, though, if you think you may use
inputsin the future.The change you propose in 3 would not work the way you expect, the
extraSpecialArgsneeds to be set for Home Manager, not NixOS. My guess is that thenixosSystemfunction simply would ignore theextraSpecialArgsparameter.Ohh I see, now it makes more sense, thank you!
