    I'd also like to point out that we can do this whole process very
    incrementally. If we want, we can start out with all containers
    chroot'd into a filesystem namespace which uses read-only bind mounts
    and doesn't allow any write access to the underlying filesystem.

    As we introduce the capability checks, we can start to actually
    cooperatively share more data.
