I think that the easiest way to do this is to create my own INSTALL
kernel, with a non interactive install.sh script that replaces
distrib/amd64/installimage/install.sh. I've made a copy of installimage
and renamed that to myinstallimage,, I've also tried changing the
Makefile in distrib/amd64/ to include my folder, but so far I haven't
been able to couple the INSTALL kernel with myinstallimage, and there
doesn't seem to be much information around about how to do such a task.
If someone has experience with that I would greatly appreciate some
guidance.

Thanks, Roger.
