Bug#849008: grub-pc: grub-probe fails to find / on a LUKS encrypted ZFS-on-Linux system

[feliks]

Package: grub-pc
Version: 2.02~beta2-22+deb8u1
Severity: important

Dear maintainers,

I use zfsonlinux using the official Debian jessie-backports repository and my
ZFS root itself is contained in a LUKS volume. This setup is not recognized by
the current grub-probe version from jessie-backports (2.02~beta2-22+deb8u1) and
gives the following error message:

> /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).

However, using the current version from the testing repository (2.02~beta3-3),
I can confirm this to be not affected anymore. Would it be possible to get the
working newer version to the jessie-backports repository?

Bug #706415 [0] seems to be connected with my problem.

Thanks,
  feliks
