Title:
  Cannot recreate md1 if partitions (ie: md1p1, md1p2) detected

Status in partman-auto-raid package in Ubuntu:
  Confirmed

Bug description:
  distribution: trusty
  package: partman-auto-raid
  Version: 22ubuntu1
  file: ./lib/partman/display.d/55initial_auto_raid_fs
  function: fix_raid_fs
  lines: 22-29

  Hi,

  On non-partitioned disks, partman-auto-raid worked perfectly fine for
  me. Re-installing just after previous install worked fine, too.

  However, if one of the created raids gets partitioned (ie: md1p1,
  md1p2) and a re-install is run, partman-auto-raid fails with "Error:
  incorrect directory for /dev/md1".

  By wiping disks partitions out (ie: dd if=/dev/zero of=/dev/sda ...),
  under partman/early_command, RAID is not detected and partman-auto-
  raid works again.

  partman-auto-raid should automatically partition disks no matter their
  previous state.

  Please let me know if you would require further details.

  Cheers,
  -Alvaro.
