Thanx for the report. I think I could see the scenario. Please test this patch. You will need "acl" mount option for aufs to gain the full support of posix-acl. By the way, Justin's original post to this ML was not delivered to me. I just got one line "cc @sfjro" msg from him, which was posted to https://github.com/docker/docker/issues/30245. And I replied to github only. Although I could read the same post on github, it was fortunate for me that you replied to his post. Otherwise I could find the post much later. J. R. Okajima
