The correct fix for this is to link in libzfslinux-dev to get smarter
zfs polling, instead of parsing output of "zpool" command.

Title:
grub-probe for zfs assumes all devices prefix with /dev, ignoring
/dev/disk/...
Status in grub:
Unknown
Status in grub2 package in Ubuntu:
Confirmed
Bug description:
update-grub runs /usr/sbin/grub-probe
/usr/sbin/grub-probe runs ["zpool", "status", poolname]
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
