如何在Nix中组合两个列表？

Question

我目前有一个列表定义为:

   environment.systemPackages = with pkgs; [
     acpi
     ag
     alacritty
     audacity
     awscli
     bash
     breeze-gtk
     cabal-install
    ];

我如何定义两个列表然后合并它们来设置environment.systemPackages值？

我想拆分列表,以便更容易管理相关包的组.

该++操作:

nix-repl> [1 2 3]  ++ [5 6]
[ 1 2 3 5 6 ]

代码示例:

let
  unstable = import <unstable> {
    config = config.nixpkgs.config; 
  };
  examplePkgs = with pkgs; [
    bash
  ];
in
{

   environment.systemPackages = with pkgs; [
     google-chrome
   ]
   ++ examplePkgs;
