Bug#567437: [grub-common] grub-probe uses a wrong grub partition number ((hd0, 5) for /dev/hda5, correct:(hd0, 4))

[Lutz Lehmann]

Package: grub-common
Version: 1.98+20100706-1

--- Please enter the report below this line. ---
Per specification, grub partitions are counted from 0, in the /dev system, 
counts start with 1. So the correct translation is

/dev/hda1 --> (hd0,0)
/dev/hdb5 --> (hd1,4)

etc.

grub-probe seems to translate first the dev partition name to a grub name, 
/dev/hda5 to (hd0,5), and then uses this wrong partition name to access 
the partition properties. Which gives a problem if there is only one 
partition.

Worst, this wrong partition is then also used in grub.cfg, rendering the 
system unbootable.
