It would be cool, to be sure!  I never used Lua before, and it was a
great experience integrating it into GRUB; Lua is very easy and clean
to integrate, and it makes adding totally customizable functionality to
themes really easy.

I haven't had a chance to really discuss the possibility of Lua support
with the core GRUB developers, however.

My plan was to modularize Lua in such a way that it is an optionally
loadable piece of the gfxmenu functionality.  Currently the Lua branch
has a hard dependency on Lua.

Actually, I think replacing GRUB's "bash-ish" scripting with Lua would
be great in many ways, but it is true that Lua (at ~100 KB) is larger
than the GRUB script engine.
