Bug#533466: errors during postinst: GPT partition label, embedding impossible

[martin f krafft]

Package: grub-pc
Version: 1.96+20090603-2
Severity: normal

The installation yields warnings/errors during postinst:

Setting up grub-pc (1.96+20090611-1) ...
grub-setup: warn: This GPT partition label has no BIOS Boot Partition; embedding won't be possible!
grub-setup: error: Embedding is not possible, but this is required when the root device is on a RAID array or LVM volume.
Invalid device `/dev/vdb'.
Try ``grub-setup --help'' for more information.
Generating grub.cfg ...

The system still boots.

vdb does not seem to be referenced anywhere:

mdadm-lab:~# grep -r vdb /etc/grub.d /etc/default/grub /etc/fstab /boot/grub || echo none
none

Running grub-install /dev/md0 works:

mdadm-lab:~# grub-install /dev/md0
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

(hd0)   /dev/hda
(hd1)   /dev/hdb
(hd2)   /dev/hdc
(hd3)   /dev/hdd
(hd4)   /dev/vda

(hd6)   /dev/sdb
(hd7)   /dev/sdc
(hd8)   /dev/sdd
(hd9)   /dev/sde
(hd10)  /dev/sdf

I can provide root access to the test system if it helps.
