I'm currently having the same questions in order to develop Super Grub2 
Disk out of the Grub2 source code.

The problem about grub installation is that it mixes with your own 
distribution grub installation unless you use a chroot. But you can 
avoid that by using prefixes.


Please check these files:

grub-build-001-prepare-build.sh
grub-build-002-clean-and-update.sh
grub-build-003-build-all.sh
grub-build-004-install-all.sh

at Super Grub2 Disk git:
https://forja.cenatic.es/plugins/scmgit/cgi-bin/gitweb.cgi?p=supergrub2/supergrub2.git;a=tree

Then it's just a matter of using the appropriate grub-mkrescue binary 
from the non standard installation directories (Not implemented in Super 
Grub2 Disk build scripts but soon to be implemented).
