ADMIN: How to make a Debian live image

To create a customized Debian image, we'll use live-build. Reading the Live Systems Manual is also a good idea.

We're going to do this from a running Debian Stretch system, it'll be simpler.

To "prepare" the environment (here a Stretch system w/ contrib & non-free repos enabled:

lb config -d stretch --archive-areas "main contrib non-free" --debian-installer live

If you need some special packages installed in your Live environment, the lists are in config/package-lists/ (1 package name per line)

Finally, to build the image:

lb build

If you did this on a x86_64 system, the image will by default be named live-image-amd64.hybrid.iso. To put it on a USB stick, you can use dd the normal way.
