Overlaying default grub.cfg makes qemu "fat:" partition inaccessible

[James Collier]

Hi all,
I'm using GRUB2 from svn (r2039) with qemu.
Steps I take to reproduce:
1. create an overlay directory e.g. /grub2/overlay
2. populate the directory with
        overlay/boot
        overlay/boot/grub
        overlay/goot/grub/grub.cfg
Where grub.cfg contains "some-menuentry" for example I use:
menuentry "Viengoos" {
        multiboot /viengoos -D 3 -o serial
        module /hieronymus
}

3. run (option1): 
$ cd /grub2
$ grub-mkrescue --image-type=floppy --emulation=floppy \
--overlay=overlay  grub2-boot-floppy


or (option2): 
$ cd /grub2
$ grub-mkrescue --image-type=cdrom --overlay=overlay \ grub2-boot-cdrom

4. start qemu with:
$ cd /grub2
(option 1):
$ qemu --serial stdio -hda fat:kernel-dir -fda grub2-boot-floppy -boot a
or
(option 2):
$ qemu --serial stdio -hda fat:kernel-dir -fda grub2-boot-cdrom -boot d

In the case of option 1, grub2 boots straight to the menu as expected.
Typeing 'c' to get to the prompt then 'ls' at the prompt reveals only
the (memdisk) device.
It was expected that at least (hd0,1) for the -hda fat: partition would
be available

Option: following the above and typing 'ls' at the prompt reveals
(hd0) and (hd96) where (hd0,1) was also expected as above.

qemu version 0.9.1

Thanks,

James Collier
