A "toolchain"? I only see some instructions for building a system in the style of Linux from Scratch? This guide is highly inconsistent and often does not make any sense. Why should I create a new partition on my machine? Why should I then create a new VM? Both are never referenced anywhere later on. Overall it looks like bad copy & paste of instructions from LFS, without giving any attribution or adhering to the license. Why would I want to use that instead of the much more detailed original? http://www.linuxfromscratch.org/lfs/view/stable/index.html http://www.linuxfromscratch.org/lfs/view/stable/index.html
