挂载点不存在

挂载点不存在

为了更改忘记的 root 密码,我执行了以下步骤:

从 LiveUSB 启动并运行以下命令:

sudo mount /dev/sda1 /mnt
for d in dev sys run proc; do sudo mount --bind /$d /mnt/$d; done

错误如下:

mount: mount point /mnt/dev does not exist
mount: mount point /mnt/sys does not exist
mount: mount point /mnt/run does not exist
mount: mount point /mnt/proc does not exist

有什么提示吗?

听起来你没有击中根设备。此外,与设置 chroot 相比,更方便的做法是简单地执行以下操作:

sudo mount --bind /mnt/etc/shadow /etc/shadow
sudo passwd # in the host system (!)
