OK Gary, thanks. I have found an article which states including
"read-only-rootfs" in the IMAGE_FEATURES will provide me with just
that. I am building now, so let's see what happens.

In my opinion, although a power-failure reboot is undesirable from the
OS perspective, I would expect it to come back with networking up - or
at least auto-magically reboot if they aren't for some reason.
