Hi,

Regarding the dailies version of zfs: 0.6.3-222d9d57jessie

Mounted zfs files systems are not detected by grub-probe with "error: unknown filesystem" being returned. No such issue found with version v0.6.3-766_gfde0d6d (non-dailies). I am running Debian Jessie of VirtualBox.

All packages below are version: 2.02~beta2-19 amd64
grub-efi
grub-efi-amd64
grub-efi-amd64-bin
grub2-common

Thanks for all that you do,

Azeem
