To be clear, the root issue here is super low cost hosting with partial virtualization which uses an old Linux kernel on the host that is incompatible with any filesystem Docker supports – realistically (and sadly) only aufs at this point.

Over time old kernel versions should fall away and at least one bleeding edge Union file system will make it into Linux proper.
