Ok... with 'snapshot' it works (I tried it yesterday and it didn't -
probably a manipulation issue).

I note then that we have a MACHINE= issue and the docs are out of sync
https://docs.yoctoproject.org/dev/brief-yoctoprojectqs/index.html#building-your-image

I can submit a docs fix (there are more things not up to date) when this is
solved: is this option necessary now or it will be hidden in runqemu?
