This approach might force you to manually mount the root filesystem containing /etc ... and then you can change the root password, unmount and reboot. Then you can enter single user with a known password. If you save the root password stored in /etc/shadow before you change the password, you can also restore the old root password if that's needed afterwards. kind regards, David Sommerseth
