Q1. In /boot/grub/grub there are many references to a UUID.
Where does grub get this reference? I would like to change the source and then run update-grub.
I prefer not to edit the grub file manually because then when I do run update-grub the UUID will come back.
Q2. There are some obvious drawbacks to using UUID's in grub and fstab, but what are the advantages for a home desktop user?
I can't think of any but there must be some.
