Details:

grub-probe fails to identify /dev/mapper/loop0p1. I have tried a workaround
of:
ln -s /dev/mapper/loop0p1 /dev/loop0p1
to no effect.

to reproduce;
1. create a disk image with dd.
2. losetup the image
3. partition the image
4. kpartx /dev/loop0 (to create /dev/mapper entries)
5. put filesystem on image
6. mount /dev/mapper/loop0p1 /mnt/image
7. debootstrap to the image
8. create /mnt/image/boot/grub/device.map with:
  (hd0) /dev/loop0
9. grub-install --root-directory=/mnt/image /dev/loop0
