grub2 (2.02~beta2-36ubuntu5) yakkety; urgency=medium

  * debian/patches/zpool_full_device_name.patch: Signal to zpool that
    it should emit full names of constituent devices.

** Changed in: grub2 (Ubuntu)
       Status: In Progress => Fix Released

** Description changed:

+ [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.

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.
