Bug#600578: grub-common: grub-mkrelpath does not return any output when processing non-root ZFS filesystems

[Jordi Mallach]

Package: grub-common
Version: 1.98+20100804-4
Severity: serious
Tags: fixed-upstream

grub-mkrelpath detects and correctly processes root ZFS volumes. However,
it does not return anything when processing any other ZFS volumes.

To make it more obvious, these are the results of tests on a system setup
with a ZFS volume for /, and an additional ZFS volume for /boot (needed as
GRUB does not support ZFS with volume arrays).

//@/usr
dkfbf1:~# grub-mkrelpath /boot

This breaks grub.cfg generation on this kind of GNU/kFreeBSD setup, and is
already fixed upstream in commits 2881..2883:
