The serial console doesn't work with Firefox, but works fine with Chromium.

Use boot script for this, not local boot.

Navigate to Instances -> [Your Instance] -> Advanced Settings.

Make sure only ``INITRD_POST_SHELL=1`` is present in tags.

Reboot the instance. You'll get a shell with the rootfs volume of the VM you're
|
|
|
|
|
restoring the password mounted in ``/newroot``, e.g:
|

|
|
|
|
|
|
|
|
.. code-block:: bash
|
|
|
|
|
|
|
|
|
|
chroot /newroot
|
|
|
|
|
passwd root
|
|
|
|
|
|
2019-08-23 10:59:21 +02:00
|
|
|
Exit the chroot shell and the post initrd shell, the boot process will
|
|
|
|
|
continue, loading the updated rootfs.
