I just saw this go by on planet.fedoraproject.org::

notting or jeremy: Is markmc working on something like this as part of
stateless or is the devicemapper work he's doing totally unrelated?
It's related, but it's not part of the readonly-root support. Using
something like device-mapper for that means you'd have to use a block
device.
What LFS appears to be doing is creating a sparse loop device on tmpfs,
and using that as the block layer. It's a interesting idea, and bears
investigation.
