I've got a few patches to runc/docker to take care of most of it.  When those
are merged, you'll need

1. a cgroup-namespace kernel (and the ubuntu unprivileged overlay kernel)
   I should probably put these in a ppa.
2. the overlay docker driver
3. hide apparmor (echo 0 > aa; mount --bind aa /sys/module/apparmor/paramaters/enabled)
4. probably rm $base_image/dev/shm because of a kernel bug which i'm hoping we fix
soon

Yeah use overlay.  btrfs may work.
