我使用 Debian 9 和带有 LABEL 的 Grub 安装了我的服务器。在我的/etc/fstab我看到我的标签如下：
LABEL=root / ext4 errors=remount-ro 0 1
/dev/sr0 /media/cdrom0 udf,iso9660 user,noauto 0 0
但我在我的/boot/grub/grub.cfg
linux /boot/vmlinuz-4.9.0-3-amd64 root=**/dev/sda1** ro single
如何将设备更改为我的标签？

使用blkid或e2label /dev/sda1获取分区标签然后将其替换到您的 中fstab， fileroot中的选项grub.cfg不同，它用于设置根文件系统。
将以下行添加到您的/etc/defaut/grub：
GRUB_DISABLE_LINUX_UUID=true
GRUB_ENABLE_LINUX_LABEL=true
然后编辑您的 2 行，/boot/grub/grub.cfg如下所示：
search --no-floppy --label root --set=root
linux /boot/vmlinuz-4.9.0-3-amd64 root=LABEL=root ro single
