No I don't have all the answers I'm just trying understand the best approach to a liveCD based system without needing extra compiling tools on the LiveCD. I was under the impression that once you compile (make) a package from source with your toolchain that it doesn't require the toolchain after that. But what it does need are any dependencies from libraries, which we would need to install before installing the package we want. It has been said that chapter 6 is building more of the required packages that we will need for other packages, so in other words just common dependencies and common compiling tools?
