I have written a shell script, which creates a Virtual Box Image via VBoxManage (http://www.virtualbox.org/manual/ch08.html). I have also attached a Debian netinst iso image to it. When I now start the image I see the Debian installation start menu. How can I do the Debian installation headless via the shell script?
I have created a project to solve this exact problem. It automatically generates a Debian VirtualBox appliance from a Debian ISO from start to finish.
