Title:
  fdisk fails to recognize OpenBSD partition (type A6)

Status in “util-linux” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: util-linux

  fdisk claims to support editing *BSD disklabels, yet fails to
  recognize an OpenBSD partition created by fdisk itself:

  <code>
  jani at saegusa:~$ LC_ALL=C sudo fdisk /dev/sdc

  WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
           switch off the mode (command 'c') and change display units to
           sectors (command 'u').

  Command (m for help): p

  Disk /dev/sdc: 1053 MB, 1053032448 bytes
  1 heads, 6 sectors/track, 342784 cylinders
  Units = cylinders of 6 * 512 = 3072 bytes
  Sector size (logical/physical): 512 bytes / 512 bytes
  I/O size (minimum/optimal): 512 bytes / 512 bytes
  Disk identifier: 0x001411b2

     Device Boot      Start         End      Blocks   Id  System
  /dev/sdc1             342      342784     1027328   a6  OpenBSD

  Command (m for help): b
  There is no *BSD partition on /dev/sdc.
  </code>

  "*BSD" implies OpenBSD, yet apparently it is unsupported.

  If I change the partition type to A5 (FreeBSD), fdisk does allow me to
  create a disklabel:

  <code>
  Command (m for help): t
  Selected partition 1
  Hex code (type L to list codes): a5
  Changed system type of partition 1 to a5 (FreeBSD)

  Command (m for help): p

  Disk /dev/sdc: 1053 MB, 1053032448 bytes
  1 heads, 6 sectors/track, 342784 cylinders
  Units = cylinders of 6 * 512 = 3072 bytes
  Sector size (logical/physical): 512 bytes / 512 bytes
  I/O size (minimum/optimal): 512 bytes / 512 bytes
  Disk identifier: 0x001411b2

     Device Boot      Start         End      Blocks   Id  System
  /dev/sdc1             342      342784     1027328   a5  FreeBSD

  Command (m for help): b
  Reading disklabel of /dev/sdc1  at sector 2049.
  /dev/sdc1  contains no disklabel.
  Do you want to create a disklabel? (y/n) 
  </code>

  At the very least, "*BSD" should be changed to indicate which types of
  BSD partitions are actually supported (FreeBSD, maybe others?).

  Better yet, have fdisk actually support editing OpenBSD disklabels as
  well.
