I am also experiencing this. Seems like debian already fixed it:

If I do not have aufs-tools installed, docker complains:
Jul 21 17:59:25 c7-n2b43-cibuild dockerd[22858]: time="2017-07-21T17:59:25.392652902-06:00" level=warning msg="Couldn't run auplink before unmount /var/lib/docker/aufs/mnt/b716be83f20c98bbb917619fd182c8d4f941ae3ef2dda591320475873a8ebeb0-init: exec: \"auplink\": executable file not found in $PATH"

But if I install aufs-tools, I get cores nearly every time docker has been run.
