HOWTO create a Linux LiveCD

I’m working on a project that calls for a Linux LiveCD, so it can be booted off of a CD-ROM or USB drive, and not require any sort of permanent install to run. You’ve probably seen this in things like Ubuntu’s LiveCD where you can try the latest version without having to install it, or you can even install it from within the Live environment, but I’m not trying to do that. I just want a Linux environment running and providing DHCP and other network services for the network it finds itself on. While I found some great HOWTOs online, most were outdated, or just didn’t do all that I wanted, so it was time for a new one. Now, since this is going to target a server role I’m going to be kicking it with Debian, and they have a set of tools called Live Tools to assist in the building of a Debian LiveCD. This method requires working from an existing Debian instance, so get there, and then update your /etc/apt/sources.listto include the Live Tools
