Bug#517563: After installing grub to /dev/sdb with root filesystem on /dev/sdb, grub attempts to load root filesystem from /dev/sda

package: debian-installer
version: 20090123

After installing grub to /dev/sdb with root the filesystem on
/dev/sdb, grub attempts to load the root filesystem from /dev/sda.

Apparently, grub thinks whichever hard drive it is loading from is the
first hard drive, even if Linux thinks it is the second.

Workaround: Manually modify grub's menu.lst

There will be a line that says something like "root (hd1,4)". Change
the first number to zero, so that example should be changed to "root
(hd0,4)".
