*** Given the process to build the Marshmallow AOSP, I am going to make an external drive bootable with the ubuntu live cd, and build from there. I suspect that this will take a week to accomplish, but I don't want to make a bunch of changes to my system by installing old packages when what I want in the end is to build more current versions of Android anyway.

Additionally, I need to work this out so that I can build the Linux Kernels on an external drive, as well as experiment with building and installing drivers within a kernel, so I don't make my system inoperable.
