Does grub2 have a means of selecting a menu entry by a unique label instead of the current numbering system which results in commands like grub-reboot '1>3', GRUB_DEFAULT=1, GRUB_DEFAULT=1>3?What I have in mind are more line the UUIDs used for selecting partitions to boot from, rather than expressions like (hd0,1), (hd1,1) etc. I would prefer to enter random UUIDs in the menu entries and use GRUB_DEFAULT=MENUID=2XDR rather than numbered entries which are hard to compute?
Does Grub2 have a way of uniquely labelling the menu entries that can be used to set the default for booting?
grub2;uuid;defaults
