Ubuntu Installation :: Experts - Please Grade My 40_Custom Grub Script

Related to my last post.

This post was me trying to get GeeXboX working on my computer.

I had no idea how to edit GRUB2 and initially posted my first effort below:

#!/bin/sh
exec tail -n +3 $0

menuentry "GeeXboX 1.2.4 for x86_32 (PC, MacIntel)" {
set root=(hd0,5)
linux /GEEXBOX/boot/vmlinuz root=/dev/ram0 rw rdinit=linuxrc root=UUID=d46e2773-aba9-41b3-a36b-fc3a6710a474 lang=en keymap=qwerty splash=silent quiet
initrd /GEEXBOX/boot/initrd.gz
}
