I get this error when I try to build a docker file
error creating aufs mount to /var/lib/docker/aufs/mnt

If you try to use docker inside a persistent enable Live CD, you may encounter this error. I guess, it is due to the fact that you can't mount aufs inside overlayfs mounts, which is the persistent layer.
The solution was simply using different driver. I've used vfs
in /etc/docker/daemon.json
Here it is
{
"storage-driver": "vfs"
}
