Bug#848945: grub-common: Empty rpool leaves ZFS systems unbootable

Package: grub-common
Version: 2.02~beta2-22+deb8u1
Severity: important
This problem likely stems from the use of grub-probe in grub-mkconfig.
For a zpool, grub-probe may very well display several lines of
information. Unfortunately, an analysis of strace shows all this goes
into GRUB_DEVICE and gets passed along in the future.
However, it may also be that grub-probe returns "unknown filesystem" for
zfs.
