Title:
  preseed Lucid with RAID and LVM fails to boot

Status in mdadm - Tool for managing linux software RAID arrays.:
  New
Status in partman-auto-raid package in Ubuntu:
  New

Bug description:
  Binary package hint: partman-auto-raid

  System fails to boot after preseed Lucid (10.04) to create RAID1 + LVM
  partitions:

  1. I can never preseed away the question to confirm that the partition should be committed (d-i partman-md/confirm boolean true)
  2. after reboot, /dev/md1p1 is assigned to /dev/sda and /dev/sdb, even though I explicitly had /dev/sda1+/dev/sdb1 as /dev/md0 and /dev/sda2+/dev/sdb2 as /dev/md1

  Note: I manually remove all the partitions from the disks (fdisk
  /dev/sda ... o ... w), including using mdadm --zero-superblock to
  remove all the information for the arrays.

  After rebooting, the system dumps me to a shell where I can manually
  "fix" things. fdisk -l /dev/sda and /dev/sdb show the right

  Attached is a copy of the preseed file I'm using.

  Here is the debian instructions

  raid-recipe.txt

  I opened this Forum post looking for answers, but at this point, after
  much testing, this looks more like a bug:

  Hopefully this is a trivial thing to fix.

  Hardware:
  - Sun Workstation Ultra20 m2
  - 2 Seagate 500G disks
