Xavier AGX: Firmware autoupdate results in build errors

[maleadt]

Running with hardware.nvidia-jetpack.firmware.autoUpdate, rebuilding the OS yields:

warning: error(s) occurred while switching to the new configuration

Just curious, did you somehow configure your NixOS system to not have coreutils in your PATH? Either way, this looks like something we can fix, but these are a class of errors that I commonly miss....

Not explicitly, no. I'm fairly new to Nix, and using a very simple config. Relevant pieces of it:

{ config, lib, pkgs, ... }:

{
  imports =
      ./hardware-configuration.nix
      (fetchTarball "https://github.com/anduril/jetpack-nixos/archive/master.tar.gz" + "/modules/default.nix")
    ];

  hardware.nvidia-jetpack.enable = true;
  hardware.nvidia-jetpack.som = "xavier-agx";
  hardware.nvidia-jetpack.carrierBoard = "devkit";
  #hardware.nvidia-jetpack.firmware.autoUpdate = true;

  # Use the systemd-boot EFI boot loader.
  boot.loader.systemd-boot.enable = true;
  boot.loader.efi.canTouchEfiVariables = false;


  ## software

  services.nvpmodel = {
    enable = true;
    # MODE_30W_ALL
    profileNumber = 3;
  };

  environment.systemPackages = with pkgs; [
      # essential CLI utilities
      ripgrep
      fd
      screen
      ncdu
  ];
