So I just did a test of using OverlayFS on Fedora Atomic 25 as a
cloud-init option. This resulted in having the whole disk as one volume, shared with the
overlay, instead of multiple partitions. That's the desireable default setup, I think.
Am I missing something?
That is one way to set it up, but I believe @vgoyal @walters and @dwalsh still want a
separate filesystem to back the overlayfs so that your docker storage can't canibalize
your root filesystem. This is more "production" like. So here with overlayfs we
gain the ability to "re-use" the rootfs if we want to, or to set it up similar
to how we were doing it in the past with DM. The "requirement" of the separate
fs in the past was the PITA part that new users didn't understand. Now we can do it
