I'm setting the package to partman-auto.  I hope this is correct.

Title:
  lvmok not respected in partman-auto/expert_recipe after netboot asks
  "Select disk to partition"

Status in “partman-auto” package in Ubuntu:
  New

Bug description:
  This is a netboot issue.  I'm not sure what package this is associated
  with.

  If I have only one disk on a server my preseed config (attached) works
  as expected and creates lvm partitions defined in my expert_recipe.

  If I have two disks then netboot asks me to "Select disk to
  partition".  Once it has asked me this it partitions the disk using
  extended partitions rather than lvm partitions thus ignoring the lvmok
  argument in the expert_recipe.  The created partition correspond to
  the sizes and names of the partitions in the expert_recipe so it is
  still reading this section of the preseed file, but they aren't lvm's.

  I can reproduce this on multiple system types including virtualbox,
  esx, hardware.  This example is using a VirtualBox virtual machine.

  trusty.cfg - preseed config I am using which exhibits this issue.  I
  redacted a few values.

  selectdisk.png - screenshot of the disk prompt
  goodpart.png - screenshot of the partitioning with one disk.
  badpart.png - screenshot of partitioning with two disks.

  syslog - /var/log/syslog log up to the point where netboot has chosen to use extended partitions
  partman - /var/log/partman log up to the point where netboot has chosen to use extended partitions.

  Please let me know if there is any more information I need to provide.
