Arch linux:具有arch内核和lts内核的系统引导菜单

Question

我希望能够在启动时选择内核。我已经安装了arch默认值和lts内核。我使用systemdboot作为引导加载程序。

但当我启动我的笔记本，它直接启动，没有显示任何菜单。当我运行uname -r时，我得到：

5.9.0-arch1-1

在/boot/loader/entries/中，我有两个文件：

arch.conf

title Arch Linux
linux /vmlinuz-linux
initrd /intel-ucode.img
initrd /initramfs-linux.img
options root="LABEL=arch_os" rw

和拱形

title Arch Linux (LTS)
linux /vmlinuz-linux-lts
initrd /intel-ucode.img
initrd /initramfs-linux-lts.img
options root="LABEL=arch_os" rw

在/boot中，我有：

drwxr-xr-x 7 root root 4.0K 11. pro 11.08  EFI/
-rwxr-xr-x 1 root root  28M 26. led 16.39  initramfs-linux-fallback.img*

-rwxr-xr-x 1 root root 6.2M 25. led 16.19  vmlinuz-linux-lts*

当我运行bootclt时，我得到：

解决方案是在/boot/loader/loader.conf中设置超时参数：

default arch.conf
timeout 5
console-mode max
editor no
