grub-mkconfig 未填充 /etc/grub.d/10_linux 菜单条目 (Void Linux)

grub-mkconfig 未填充 /etc/grub.d/10_linux 菜单条目 (Void Linux)

我一直在编写脚本来安装 Void Linux（我需要比 void-installer 更精细的东西）。我能够在 UEFI 上顺利安装 grub，但 BIOS 安装不起作用。

我grub-install /dev/sda这样做可以正常工作，但运行grub-mkconfig -o /boot/grub/grub.cfg会生成一个配置，其中缺少 Void 的菜单项（例如应该从/etc/grub.d/10_linux（我已检查过它确实存在））。

grub-mkconfig这可能是因为我在 chroot 中运行，但grub-install --target=x86_64-efi --efi-directory=/efi --bootloader-id="Void"运行正常。但这可能是因为 UEFI 的工作方式不同。

这是我的脚本中负责安装引导加载程序的函数：

install_bootloader() {
    display_logo
    echo "------------------------------------"
    echo "(8) Install bootloader"
    echo "------------------------------------"
    read -p "Enter system architecture (x86_64|aarch64): " arch
    exit_if_0 $arch
    read -p "Enter system disk (e.g. /dev/sda): " disk
    exit_if_0 $disk
    read -p "Enter boot partition (e.g. /dev/sda1: " boot_partition
    exit_if_0 $boot_partition
    read -p "Enter boot partition scheme (boot|efi): " boot_scheme
    exit_if_0 $boot_scheme
    read -p "Enter root partition (e.g. /dev/sda2): " root_partition
    exit_if_0 $root_partition
    if [[ $boot_scheme == "efi" ]]; then
        if [[ $arch == "x86_64" ]]; then
            xbps-install grub-$arch-efi
        elif [[ $arch == "aarch64" ]]; then
            xbbps-install grub-arm64-efi
        fi
    fi
    if [[ $boot_scheme == "efi" ]]; then
        mkdir -p /efi
        mount -o rw,noatime $boot_partition /efi
        if [[ $arch == "x86_64" ]]; then
            grub-install --target=$arch-efi --efi-directory=/efi --bootloader-id="Void"
        elif [[ $arch == "aarch64" ]]; then
            grub-install --target=arm64-efi --efi-directory=/efi --bootloader-id="Void"
        fi
    elif [[ $boot_scheme == "boot" ]]; then
        mount -o rw,noatime $boot_partition /boot
        mkdir -p /boot/grub
        grub-install $disk
        sleep 3
        grub-mkconfig -o /boot/grub/grub.cfg
        sleep 3
    fi
    clear
}

这是我得到的 /boot/grub/grub.cfg：

有任何想法吗？

先感谢您。

事实证明，这是因为我试图在调用 grub-install 和 grub-mkconfig 之前立即挂载 /boot 分区 - 这是不必要的。我删除了挂载调用，之后它就正常工作了。我查看了官方 void-installer 脚本，并假设我必须调用“chroot grub-install...”和“chroot grub-mkconfig...”，但事实并非如此，这只是挂载。
