I'm sending this RFC for discussion and high-level suggestions.  Since
I'm still quite new to buildroot, I'm hoping to learn how to better/more
idiomatically design this patch series.

Thanks in advance for any review.

Note that while the rootfs appears so far to be as-expected, outstanding
kernel/hypervisor bugs remain under investigation.  I'd like to use buildroot
to simplify collaboration among contributors.
