Problem with GRUB

[Olof Mattsson]

Hi

The problem seem to be in the "config/files/boot/grub/menu.lst/postinst"
script for GRUB.
When i change the line:
[ -r $target/var/log/fai/disk_var.sh ] && .
$target/var/log/fai/disk_var.sh

to
[ -r $target/var/log/fai/disk_var.sh ] && . /tmp/fai/disk_var.sh

GRUB is installed on both hard drives. The variable $target doesn't seem
to be available for the "postinst" script. When I add the static path to
the "disk_var.sh" file it works.
Even though it seems so work the script complains about /dev/md0 as
$BOOT_PARTITION. I get the error: 
Can't match device: /dev/md0
