then why does the search still use the --fs-uuid option even though
GRUB_DISABLE_LINUX_UUID is set to true and uncommented?
should the "set root=(hdX,Y)" command not take care of the location
for grub to look for its files?
in some cases the search seems to be looking for different UUID's
than those passed by the command (set in grub.cfg).
