In Ubuntu 16.10 the kernel configuration CONFIG_AUFS_XATTR=y has been omitted.
Test:
16.10
$ grep AUFS_X /boot/config-4.8.0-22-generic
CONFIG_AUFS_XATTR is not set
16.04:
grep AUFS_X /boot/config-4.4.0-42-generic
CONFIG_AUFS_XATTR=y
Without CONFIG_AUFS_XATTR docker users using the AUFS driver can not use the image
