  * Force formatting as btrfs filesystem, to bypass mkfs.btrfs
    safety-check that target (possibly) contains existing filesystem when
    formatting partitions with btrfs. (LP: #1276356)

Title:
  partman-btrfs fails to format as btrfs filesystem

Status in “partman-btrfs” package in Ubuntu:
  Fix Released
Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  mkfs.btrfs does extra checks to see if location it's formatting
  appears to contain any other filesystems.

  Instead it unhelpfully prints a message to stderr:

  /dev/sda6 appears to contain an existing filesystem (crypto_LUKS).
  Error: Use the -f option to force overwrite.

  And exits non-zero, which results in partman-btrfs to throw a generic
  error of "failed to create partition". Well, if I've asked a partition
  to be formatted with a given filesystem in the installer, I do want to
  do that...
