Bug#375265: preseeding partman-auto/disk don't work if you want lvm partitions
when making a ccd, or just a regular preseeded installation, one may want to preseed the partitioning and use lvm on the disks.
if you preseed with forinstance
partman will partition the first disk detected, but not use lvm on it.
i wish for a preseed template for instance
It would do in essence the same, but with lvm.
