Very very trivial. As u know when u boot into single mode, yr filesystem
is read-only.(Mandrake behaves diffrently). First boot into single user
mode and at the prompt :

# mount / -o remount,rw

This will remount the "root" as read-write. So now u can go into
/etc/passwd and add the deleted entry like

root:x:0:0::/root:/bin/bash

Save the file and reboot. That's it !!. U can use chage to "renew" yr
expired root account, if that's yr problem

Hope this helps..Any guys interested in making a LOST of it ??
