This work is based on debian-cd team work and uses,
as much as possible, the same mkisofs options
than the Debian Installation CD disk does.
It assumes that /boot/grub/grub.cfg (and other design items)
is generated by: binary_loopback_cfg .
It relies on efi-image and grub-cpmodules being setup
as build scripts on live-build package.
In the future event of these two files being moved
to a binary package (they are originally from:
src: live-installer) the binary_grub-efi script would have
to be rewritten to take the new paths into account.
