It can be >a bit cryptic in places, The last time I looked at pinfo grub (note the 'p', info itself is a POS) cryptic was not the description that came to my mind.

Therefore the previous posts in this and other previous threads, claiming that the drive/partitions UUID's were part of the initrd.img, are in fact bogus. But, given the lack of _good_ info on how grub really works, (IMO docs should be complete enough that the function could be re-written based entirely on the documentation available) such an obviously erroneous conclusion could easily be drawn.
