Bug#248676: partconf: incorectly detects partition type

[Eugeniy Meshcheryakov <eugen@univ.kiev.ua>]

Package: partconf
Version: d-i netboot, today
Severity: important
Tags: d-i


  Partconf incorectly detects partition types in d-i. Two examples

1. Create ext3 partition with d-i. Save changes. Change type of the
partition to LVM PV. Save changes. Run find-partitions: partition type
is ext3!

2. Create fat32 partition. Save changes. Change type of the partition to
ext3. Save changes. Run find-partitions: partition type is ext2!


>From second console I tryed tried following:
I have created LVM PV from d-i. find-partitions detects if as ext3. I
run:

   dd if=/dev/zero of=/dev/ide/<...>/part1 bs=512 count=3
   pvcreate /dev/ide/<..>/part1

After that find-partitions report this partiton as LVM. Values 1 and 2
for count did not work.

Incorect detection of LVM PVs breaks LVM configuration in d-i.
