Forgot to mention that this patch also disables the splash screen and 
makes sure there's a 10 second timeout. If you don't want those changes, 
but do want to save your last boot as the next default boot option. you 
only need to change GRUB_DEFAULT and add GRUB_SAVEDEFAULT as shown in 
the patch. I did comment out GRUB_TIMEOUT_STYLE but I'm not sure it is 
needed. For more details see the grub documentation, especially section 6.1:
