The [serial] console doesn't work with Firefox, so install Chromium.

.. important::
|

|

Use bootscript for this, not local boot.
|

|

Instances -> Select Your Instance -> Advanced Settings.
|
||||
|
||||
Make sure only ``INITRD_POST_SHELL=1`` is present in tags.

Reboot instance. You'll get a shell with the volume mounted in ``/newroot``.

Exit the chroot shell and the post initrd shell, the boot should continue to
