The idea is to have something that is easy to read for non-Nix native developers.

Compare this:

nixDirAliases = {
  nixosModules = [ "nixos/modules/*" ]
};

To this:

nixDirAliases = {
  nixosModules = lib.pipe ./nixos/modules [ builtins.readDir lib.attrNames (map (d: "nixos/modules/${d}"))] 
};

For how easy it is to read for someone, who has never programmed a ml-like language.

Is withOverlays not applied in nixosConfigurations?

I have added the function lib.noverby.add to withOverlay, but the function cannot be accessed?

nixosConfigurations/gravitas.nix:

devices/gravitas.nix: (nixosConfigrations has an alias to devices)

Is it possible to add functions to ModuleArgs.lib?

I need it to create helper functions for setting up nixosConfigrations.
It seems like it cannot be added using withOverlays, is there another approach?

withOverlays/lib.nix

# Overlay Flake lib as lib.noverby
(final: prev: {lib = prev.lib.extend (_: _: {noverby = prev.outputs.lib;});})

withOverlays/lib.nix

# Overlay Flake lib as lib.noverby
(final: prev: {lib = prev.lib.extend (_: _: {noverby = prev.outputs.lib;});})

It does work, if I try to access it in pkgs:

{
  pkgs,
  ...
}: {
  # Nix
  nix = {
    settings = {
      max-jobs = pkgs.lib.noverby.add 2 2;

It does work, if I try to access it in pkgs: (That is only possible in a nixosModule)

{
  pkgs,
  ...
}: {
  # Nix
  nix = {
    settings = {
      max-jobs = pkgs.lib.noverby.add 2 2;

      max-jobs = pkgs.lib.noverby.add 2 2;
