[Bug 1075176] [NEW] preseeding partman fails with "no root filesystem" if previous lvm is present

[Ralf Spenneberg]

Public bug reported:

I am trying to preseed an Ubuntu LTS 12.04 installation without using LVM.
This works fine if a previous linux installation on the same system did not use LVM.
If lvm volumes are already present on the system the preseeding partman fails and "no root filesystem selected" is displayed on the screen. Purging the MBR and rebooting the preseed installation succeeds.
My recipe:

This is very annoying because unattended installations are not really
possible.
