我在带有 LUKS 和 BRTFS 的 Arch 系统上，并且最近安装了linux-zen，但它没有显示在 grub 中的任何位置。我已经尝试过grub-mkconfig -o /boot/grub/grub.cfg，但它什么也没做，即使它这么说found linux image: /boot/vmlinuz-linux-zen。 grub-mkconfig 的完整输出如下：

另一个奇怪的部分是 my/boot/grub包含对 zen 内核的引用，但这没有反映在启动中。

所以我的问题是systemd-boot.一个简单的sudo bootctl remove步骤让我进入了 grub，尽管我的根设备的 UUID 设置错误存在一些问题，所以在卸载引导加载程序之前要小心。
