Great.  That's just what I need...MORE inspiration to do kewl things....

Thanks Michael!   

(All more the reason why I suggested doing an ALE Meeting topic of GRUB2
- for those of us who could use a primer)

Of course I could get online and read and do this solo...read it, play
with it, and learn how to do it...but sometimes it just goes better with
friends and ALE.

Cheers!
