[Bug 1006131] [NEW] GRUB2 doesn't boot OSX Partition after update (solved!)

[Ralf Luther]

Public bug reported:

After repartitioning my MBR formatted, multiboot HD GRUB would not boot my OSX partitions.
My screen only shows "Error: Drive not found   Error: file not found".
I manages to boot into the partition with SuperGrub2disk and OSX Boot disks.
By "try and error" I found out that there is something wrong in the OS-Prober script.
The boot loader did try to look for a "sleepimage" file on the partition in the wrong place.
the path in the prober-script was "/var/vm/sleepimage", but the file is located on the OSX partition in "private/var/vm/sleepimage" (OS X 10.6.8).

Changing the path in grub.cfg and under /etc/grub.d/30_os-prober to the
above was my answer.

At last, I don't know if the bug does rather affect GRUB2 than os-prober
(with finds all my OS correctly), but I hope that someone can change
this.
