You cannot "recover" the root password, but you can easily set it to
> whatever you want. Here's how:
> 1. Login to the box as a normal user, and run the 'mount' command to

> $ mount
> /dev/hdb3 on / type ext3 (rw)
> proc on /proc type proc (rw)
> [...]
> /dev/hdb6 on /usr type ext3 (rw)
> /dev/hdb7 on /var type ext3 (rw)
> So, in this case, /dev/hdb3 is your root parition, and /dev/hdb6 is
your
> /usr partition. Write both of these down.

> 4. Once you are at a prompt, create a mount point for your root
filesystem:
> $ mkdir /sys_root
> 5. Now, mount your root filesystem:
> $ mount -t reiserfs -o rw /dev/ROOT /sys_root
> Where ROOT is the device name that you noted in step 1 (in my example,
> ROOT would be hdb3).

> 6. Mount your /usr filesystem:
>
> $ mount -t reiserfs -o rw /dev/USR /sys_root/usr
>
> Where USR is the device name that you noted in step 1 (in my example,
> USR would be hdb6)
>
> 7. Bind /proc to your /sys_root/proc mountpoint:
>
> $ mount -o bind /proc /sys_root/proc
>
> 8. Create a chroot jail:
>
> $ cd /sys_root
> $ chroot /sys_root /bin/bash
>
> 9. Set your root password:
>
> $ passwd
> New UNIX password:
> Retype new UNIX password:
>
> 10. Escape from the jail, unmount your filesystems, and reboot:
>
> $ exit
> $ umount /sys_root/usr
> $ umount /sys_root/usr
> $ umount /sys_root
> $ reboot
