使用 lib.mkIf 和 lib.mkMerge 根据主机名设置配置时出错

Question

我正在尝试根据主机名设置配置

config = lib.mkMerge [
  ( lib.mkIf config.networking.hostName == "nuc" {
    config.installconfig.hardware.intel = true;
  } )

  ( lib.mkIf config.networking.hostName == "xps" {
    config.installconfig = {
      hardware.intel = true;
      workstation-components.enable = true;
      users.allow-rad = true;
    };
  } )
];

我在“nuc”处收到以下错误

error: attempt to call something which is not a function but a string.

我理解该错误，但我不确定如何构造 lib.mkIf 条件块。

有人可以帮我解决这个问题吗？

您需要将条件句的各个部分组合在一起：

let
  config = pkgs.lib.mkMerge [
    (pkgs.lib.mkIf (config.networking.hostName == "nuc") {
        config.installconfig.hardware.intel = true;
      })

    (pkgs.lib.mkIf (config.networking.hostName == "xps") {
        config.installconfig = {
          hardware.intel = true;
          workstation-components.enable = true;
          users.allow-rad = true;
        };
      })
  ];
in
  config.contents
