The GRUB device which gets used during boot is only searched with UUID
if you don't install to the disk which contains your /boot/grub.
Else the partition number gets hardcoded and drive number is read from
BIOS.
The script grub-install supports actually both, a GRUB device and an OS
one, i.e. /dev/XXX
But it's not recommended to use a GRUB device because that totally
depends on /boot/grub/device.map and that could be completely wrong.
