Netboot with NixOS

[blazp7]

I know this question is ancient, but for anyone wondering, this is what worked for me, taken from https://carjorvaz.com/posts/ipxe-booting-with-nixos

{inputs, ...}: let
  sys = inputs.nixpkgs.lib.nixosSystem {
    system = "x86_64-linux";
    modules = [
      ({
        config,
        pkgs,
        lib,
        modulesPath,
        ...
      }: {
        imports = [
          (modulesPath + "/installer/netboot/netboot-minimal.nix")
        ];
        config = {
          # custom installer configuration, most stuff is already configured by the imported module (it includes installation-device profile)
          users.users.root.initialPassword = lib.mkForce "pass123";
          users.users.nixos.initialPassword = lib.mkForce "pass123";
        };
      })
    ];
  };
  build = sys.config.system.build;
in {
  services.pixiecore = {
    enable = true;
    openFirewall = true;
    dhcpNoBind = true; # use existing DHCP server
    port = 64172;
    statusPort = 64172;

    mode = "boot";
    kernel = "${build.kernel}/bzImage";
    initrd = "${build.netbootRamdisk}/initrd";
    cmdLine = "init=${build.toplevel}/init loglevel=4";
    debug = true;
  };
}
