I don't think we explicitly tried unionfs, but both overlayfs and aufs
work fine. Look at lxc-start-ephemeral in Ubuntu for a tool that already
does that.

Essentially you can do: lxc-start-ephemeral -o <base container>
which will spawn a new clone of "<base container>" with all changes
stored on tmpfs using overlayfs/aufs.
