grub2 is pretty much the textbook definition of "overdesigned." All it has to do is transfer control to the OS... that's it. But somehow it grew code to parse filesystems, set up graphical user interfaces, load modules, and do half a dozen things that it really has no reason to do. Half the time this hairball won't even boot after you change something, because you forgot to run the correct script to refresh the other scripts, or you moved something on the disk.

Just install elilo and enjoy having a system that actually works.
