The first part about "Update ADD to use the image cache, based on a hash of the added content" doesn't affect issues related to the above, does it?<p>I am wondering specifically in relation to this question <a href="http://stackoverflow.com/questions/20856385/how-can-i-make-a-host-directory-mount-with-the-container-directorys-contents" rel="nofollow">http://stackoverflow.com/questions/20856385/how-can-i-make-a...</a>
