Bug#383282: grub: wrong partition numbers in menu.lst after upgrade

[Christoph Groth]

Package: grub
Version: 0.97-13
Severity: critical
Justification: breaks the whole system

Yesterday I upgraded my etch-system with

aptitude dist-upgrade

grub was upgraded from version 0.97-12 to version 0.97-13.  During the
upgrade the file /boot/grub/menu.lst was updated incorrectly, the
partition numbers miraculously increased by one.  What has been
(hd0,5) and /dev/hda6 was replaced by (hd0,6) and /dev/hda7 resulting
in an unbootable system.

This is the output of "diff -c menu.lst~ menu.lst"
