[Nix-dev] UEFI Grub is not running, only gummiboot

[Jascha Geerds]

Here's my UEFI specific stuff:

  boot = {
    loader = {
      efi.canTouchEfiVariables = true;
      grub.enable = true;
      grub.efiSupport = true;
      grub.device = "nodev";
      grub.version = 2;
    };

  fileSystems."/boot" =
    { device = "/dev/disk/by-label/efi";
      fsType = "vfat";
    };

You probably miss grub.device = "nodev"
