I hope so. So I add something like this:

```nix
users.users.dong = {
isSystemUser = true;
# isNormalUser = false;
    extraGroups = ["wheel" "networkmanager"]; # Enable ‘sudo’ for the user.
  };
security.sudo.wheelNeedsPassword = false;
        security.sudo.configFile = ''
                        dong ALL=(ALL) NOPASSWD: ALL
            '';
users.users.dong.group = "dong";
       users.groups.dong = {};

```

But still, when restart after `nixos-rebuild switch && reboot`, I am stopped by the login UI, if input nothing and press ENTER directly, it would tell me I have the wrong password number.  
I’ve also tried to use `isNormalUser = true;`, but nothing changed.

(Actually, I’ve tried to install NIXOS without setting root password by `nixos-install --no-root-passwd`, then I can’t login anylonger, so I have to reinstall system with a root password.)
