Can you explain why it does that?  (I've confirmed you are indeed correct)
Like the OP I would have thought it would be the same each time.
For instance - this is the same every time.

Is there a salt in there somewhere?  If so, how does grub know what the salt is?

Hopefully this doesn't qualify as thread jacking - I think the OP has
the same question.
