I'm looking to create a large ISO installation image. I will write the image to a large USB stick to use as installation media. Therefore, I may as well include all packages. How do I assemble such an image? I've read the manpage of build-simple-cdd and am none the wiser; nor have I managed to find examples online. I've also looked for .jigdo files (to use as input to jigdo-lite(1)).
