Title:
  Also use GPT partition table for disks smalle rthan 2TB

Status in partman-auto package in Ubuntu:
  New

Bug description:
  Since Grub2, Grub is also able to boot from a GPT disk even on legacy
  BIOS systems. GPT is more flexible in the naming or amount of
  partitions and more robust.

  The only 'disadvantage' I could come up with would be if someone
  decides to install a secondary OS on a legacy BIOS system that does
  not handle GPT disks after Ubuntu was installed first with a GPT disk.
  This is somewhat a rare case. Even for Window-Dualboot setups, Windwos
  is usually installed first because it nukes the boot code anyways. If
  Ubuntu is installed as a second OS, it will not re-write the partition
  table anyways.

  Thus I suggest defaulting to GPT for new partition tables (with
  protective MBR, as partman/parted should automatically do) even for
  smaller disk. :)
