Plymouth

Plymouth 是一個在啟動過程早期運行的應用程式，提供圖形啟動動畫，被大多數面向桌面的 Linux 發行版所使用。

用法

例如，您可以通過以下代碼使用 adi1090x's collection 中的啟動動畫：

❄︎ 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 = 3;
    initrd.verbose = false;
    kernelParams = [
      "quiet"
      "rd.udev.log_level=3"
      "rd.systemd.show_status=auto"
    ];

    # 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;
  };
}

在圖形的啟動過程中，可以用退出鍵（或者說 ESC）來切換在文本模式和 Playmouth 界面中切換。

If you are using LUKS encryption the password prompt may fall back to text mode. While the default bgrt theme supports graphical password entry, this may not be supported by all themes.
