Debian Serial Live Cd

I’m installing a trio of new systems at home to host some house infrastructure, and I’m using the opportunity to learn KVM. That’s it’s own set of fun, but my pressing need was for a Debian Live CD which doesn’t rely on a PC console, but rather can use a serial console. The Debian Live Tools take quite a bit of effort to wrap my head around, and my first attempt, building a Live CD just following the manual, did not work.
