Bug description:
  Binary package hint: btrfs-tools

  current btrfsck on natty reports:
  couldn't open because of unsupported option features (2).
  fsck.btrfs: disk-io.c:683: open_ctree_fd: Assertion `!(1)' failed.
  ...if invoked on the standard root/home.

  Meaning that when the link fsck.btrfs -> btrfsck was enabled as per Bug #660649 my system now stops booting with this message:
  fsck from util-linux-ng 2.17.2
  fsck from util-linux-ng 2.17.2
  fsck from util-linux-ng 2.17.2
  couldn't open because of unsupported option features (2).
  fsck.btrfs: disk-io.c:683: open_ctree_fd: Assertion `!(1)' failed.
  Warning... fsck.btrfs for device /dev/sda5 exited with signal 6.
  mountall: fsck /home [313] terminated with status 8
  mountall: Unrecoverable fsck error: /home
  couldn't open because of unsupported option features (2).
  fsck.btrfs: disk-io.c:683: open_ctree_fd: Assertion `!(1)' failed.
  Warning... fsck.btrfs for device /dev/sda5 exited with signal 6.
  mountall: fsck / [312] terminated with status 8
  mountall: Unrecoverable fsck error: /
  /dev/sda1: clean, 233/48768 files, 44709/194560 blocks
  init: udev-fallback-graphics main process (625) terminated with status 1

  If [I] is pressed to ignore errors booting can be done normally, just bypassing btrfsck completely.
