Yes, that's true. My question is that this setup will be possible? That's new to me, as right now 
AFAIK a rootfs can be only a directory.

My problem is that creating a 'standard' container with official tools will be pretty complicated.
Standard means here, that lxc-create sets up correct configuration files, the guest OS is fine 
tuned, volume is created...etc. Now it's easy, nice and comfortable, lightweight as the whole project.

That's correct and clear.
