My NixOS work machine. home-manager config is in my dotfiles.

I did not commit:

• hardware-configuration.nix
• luks.nix

Example luks.nix

{
  config,
  lib,
  pkgs,
  ...
}: {
  # LUKS Encryption
  boot.initrd.luks.devices = {
    root = {
      device = "/dev/disk/by-...";
      preLVM = true;
    };

    # Better read/write on SSD

    bypassWorkqueues = true;
    allowDiscards = true;
  };
