I tweaked it a little so it works for both nix-darwin and nixos:

{ lib, pkgs, ... }: {
  system.activationScripts.postUserActivation = {
    text = ''
      ${pkgs.nvd}/bin/nvd --nix-bin-dir=${pkgs.nix}/bin diff /run/current-system "$systemConfig"
    '';
  } // lib.optionalAttrs pkgs.stdenv.isLinux {
    supportsDryActivation = true;
  };
}
