> These aren't really very convincing arguments. In fact, the last one is a good counter point: if it were in that bad of a shape, then either opensuse wouldn't be using it as the default, or they would be getting a LOT of flack for it.
That wasn't an argument, just a note.

But not as exclusively as btrfs.

After researching my references above I came to the conclusion that
there's no longer an absolute necessity of the warning I
suggested/requested. I would say now that a warning with the information
that btrfs is certainly less stable than ext4 (not in stable-unstable-
dichotomy, but on a free scale) - based on the maturity and the
simplicity of the latter - would find one or two grateful users. I leave
this to you now and am available for further questions.

Title:
  add btrfs instability warning to installation routine

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  The Ubuntu installer (e.g. in live session) offers to format partition
  with btrfs, setup mount points and even install on it. Regarding the
  still unstable state of btrfs, especially with kernels of the current
  latest version (14.10 with 3.16.x) and the latest LTS (14.04 with
  3.13.x), the user has to be warned when any action involving btrfs
  take place during installation. The probability that he_she has read
  something regarding the great performance of btrfs without a hint
  about its instability is much too high in relation to the cost of
  putting such a warning in place.
