I don't know LFS, but if you are using grub (and you probably are), you can simply pass an 'S' kernel option in to get to single-user mode. Reset root's password from there.

If you've set a grub password, and don't know that either, then you're going to need a live cd to do the job.

Please start your own thread. It is confusing when there is more than one subject in a thread. For your question it will help if you say which country you are in.

Hello,

You can download any LiveCD from the internet, there's no real need to buy one. Then you can boot from the LiveCD and chroot into the harddisk environment and change the root password. Next, reboot and voila, up and running.

Once booted from LiveCD do this:

Code:

mkdir /mnt/tmp
mount /mnt/tmp /dev/sda1               <<< the partition that contains your LFS
mount --bind /dev /mnt/tmp/dev
mount -t proc none /mnt/tmp/proc
chroot /mnt/bin/bash

Now you've chrooted into a bash shell of your LFS system and can run

Code:

passwd

to reset the password.

Kind regards,

Eric
