Installation

(Optional) Enable cachix substitutions in nix.settings.

https://app.cachix.org/cache/kernel-overlay

NOTE: This change will only have effect after a `nix-daemon' restart.

  nix.settings = {
    experimental-features = [ "nix-command" "flakes" ];
    substituters = [ "https://kernel-overlay.cachix.org" ];
    trusted-public-keys = [
      "kernel-overlay.cachix.org-1:rUvSa2sHn0a7RmwJDqZvijlzZHKeGvmTQfOUr2kaxr4="
    ];
  };

Add as an input to a flake

{
  description = "OS configuration";
  inputs = {
    ...
    kernel-overlay.url = "github:andreoss/kernel-overlay";
    ...

Enable overlay

 outputs = inputs@{ self, nixpkgs, home-manager, ... }:
   let
     systems = lib.systems.flakeExposed;
     lib = nixpkgs.lib;
     eachSystem = lib.genAttrs systems;
   in rec {
     legacyPackages = eachSystem (system:
       import nixpkgs {
         inherit system;
         overlays = [
           inputs.kernel-overlay.overlays.default
         ];
       });
     ...

By default, this overlay replaces the default kernel package. To use a specific one, specify it inconfiguration.nix. For example

  boot.kernelPackages = pkgs.linuxPackages_4_14;
