Bug#983435: Regarding the backup/restore function

[bugsgrid+deb at gmail.com]

Aaaaah, my router doesn't have udev!
In osdep/linux/hostdisk.c:sysfs_partition_path(), calling udevadm
through grub_util_exec_pipe() will fail and fall through to
*unpatched* exit().
Sounds plausible?

If my guess is right, perhaps sid is affected too.
Sorry I don't have any testbed, if anyone could confirm please adjust
bugtitle and severity accordingly.  I'm not sure about appropriate
value.

... I thought a debian installation without udev is still not illegal
nor broken ...
Thanks,
