Upon further inspection, this part of grub-install is identical to the 
x86 grub-install behavior. On both architectures,
        grub-install --root-directory /foo
will install *.mod, *.lst, and the output of grub-mkimage into 
/foo/boot/grub.

I'm open to allowing an override for this, but that's not a PPC-only 
question. I guess a user uses --root-directory when they have booted 
from a CD/floppy and wish to install GRUB onto their hard disk. In that 
case, even if the hard disk's root partition has been manually mounted 
on /mnt, there is no guarantee that the firmware-accessible filesystem 
has also been mounted on /mnt/boot/grub.

Given that, Okuji, what do you think about a --grub-directory switch 
instead of (or in addition to) --root-directory?
