I have done a readonly first-boot successfully, and as Chris points out,
it is one of the policy goals. That said, I have not yet looked to see
if there are some post-inst scripts which should be run. There isn't any
kind of init going on, and we'll need to decide how to best handle that
for poky-tiny. Right now I boot using an initramfs with root=/dev/ram0,
it reads an empty /init and falls back to /bin/sh - a more robust and
functional init is probably needed even for poky-tiny.
