Title:
  batshit insane btrfs installer assume default subvolume is root
  subvolume

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  if you set the default subvolume of a btrfs volume like so
  mkfs.btrfs /dev/blasterdisk
  mount /dev/blasterdisk /mnt
  cd /mnt
  btrfs subvolume create foo .
  btrfs subvolume set-default foo .
  cd ..
  umount /mnt

  and the install WITHOUT reformatting

  then the installer will:

  1. create subvolumes foo/@ and foo/@home
  2. do no error checking: i.e. if a @ subvolume already exists, lets say you set @ as the default, then the system will install into @, and then the installer will crash while trying to mount @home (when it created @/@home)

  while your at it you should also fix upstream, and make it work
  equally bad with btrfs
