Plymouth

Plymouth 是一款在引导过程早期阶段运行，以提供图形化启动动画的应用程序，现已被大多数面向桌面的 Linux 发行版所采用。

用法

例如，你可以使用来自 adi1090x's collection 中的一个启动动画，具体操作如下：

❄︎ configuration.nix

{ pkgs, ... }: {
  boot = {

    plymouth = {
      enable = true;
      theme = "rings";
      themePackages = with pkgs; [
        # By default we would install all themes
        (adi1090x-plymouth-themes.override {
          selected_themes = [ "rings" ];
        })
      ];
    };

    # Enable "Silent Boot"
    consoleLogLevel = 0;
    initrd.verbose = false;
    kernelParams = [
      "quiet"
      "splash"
      "boot.shell_on_fail"
      "loglevel=3"
      "rd.systemd.show_status=false"
      "rd.udev.log_level=3"
      "udev.log_priority=3"
    ];
    # Hide the OS choice for bootloaders.
    # It's still possible to open the bootloader list by pressing any key
    # It will just not appear on screen unless a key is pressed
    loader.timeout = 0;

  };
}
