Could you try the attached scripts/GRUB_PC/10-setup, which is *a lot* simpler?
AFAIK grub-install takes care of a lot of things and just takes a device name as
argument, if you omit the parentheses!? It could be necessary to re-add the
grub-mkimage, if update-grub chokes on that one.

One possible issue remains: Which version of grub-pc are you using? It seems
that versions before 1.97 are broken regarding LVM.

Thanks a lot,
Michael
