For now I've pulled the first 5 patches into testing/next as they are
obvious clean-ups.

I still have concerns about this approach but I'm going to give it some
more testing. However I ran into problems testing on my aarch64 box
because of a missing gen-iso-image which makes me think we need to add
some gating via configure for tools and libraries we need.
