[Grml] Using development version of grub2

Hi all,

I need to test with grub from the developers repository. I have it cleanly compiled on grml-2011.05. How do I "grub-install" it to /usr/share/grml-live/templates/boot/grub? I think from there grml-live will include it in iso for my work. Grub-install wants a /dev/*** to write mbr and I can't do that on this box.
