This doesn't really depend on any extra steps -- I've just uploaded
grub2 and grub2-signed to xenial-proposed queue, so as soon as it's
reviewed by a member of the SRU team it will be available in proposed.

>From there, we'll need people to test this carefully to make sure
nothing is broken and that it's fulfilling its intended purposed (ie.
fixing the issue), after that we'll be able to make it available to the
general public in -updates.

Bug description:
  [Impact]
  Installs over ZFS where a ZFS disk is expected to be used as a root device.

  [Test case]
  - Run update-grub on a system with a ZFS root filesystem.

  [Regression Potential]
  Installs relying on the current broken behavior to avoid listing other operating systems in grub menu may find that new entries are added.

  ---

  update-grub runs /usr/sbin/grub-probe

  Without libzfslinux support compiled in, /usr/sbin/grub-probe runs
  ["zpool", "status", poolname] to find out ZFS info.

  zpool responds with device names as used at (I think!) pool creation
  time. Often, this is /dev/disk/by-id/... names, without the path.

  grub-probe then parses the output, and takes the names of devices, and
  if they do not start with a "/", it prepends "/dev/".

  It then tests the existence of the path name of the device. it fails.

  grub-probe then returns  something like

  /usr/sbin/grub-probe: error: failed to get canonical path of `/dev
  /ata-ST31000333AS_99999999-part1'.

  The actual path is of course /dev/disk/by-
  id/ST31000333AS_99999999-part1

  It can prepend smarter than "/dev" or it can understand ZFS natively,
  to fix the problem.
