Stored in _where_?

/dev/sda2 and /dev/sdb2 provide a software RAID0 (/dev/md0).
The PC is supposed to boot from /dev/md0p3. /dev/sda1 and
/dev/sdb1 were the /boot partitions I had used for the old
grub. /dev/sdc and /dev/sdd do not provide a boot filesystem.

On the next reboot the list of partitions might look completely
different, while the "GET" command shown above still says
"0 /dev/sda, /dev/sdb". Is this correct?

Would you suggest to move to GPT? AFAIK is supports UUIDs on
partition level, but I do not know if grub2 makes use of it.


Looking closely I found a problem with grub-probe at install
time of 20100128:

If I move back to the testing version, then I get

This is _without_ reboot, i.e. the partition list is the same
as shown above.  /boot/grub/device.map says after installing
20100115:

(hd0)   /dev/sda
(hd1)   /dev/sdb
(hd2)   /dev/sdc
(hd3)   /dev/sdd


Hope this helps. Regards

Harri
