Use "docker load" to create "scratch" in hack/make/test-integration-cli (instead of implicitly pulling it from the index) Creating the "docker save" tarball for "scratch" is pretty simple. I've also extrapolated the "docker build -t busybox ." logic into a separate "hack/make/.ensure-busybox" file so that it can eventually be reused easier.

Make `FROM scratch` a special cased 'no-base' spec There has been a lot of discussion (issues 4242 and 5262) about making `FROM scratch` either a special case or making `FROM` optional, implying starting from an empty file system. This patch makes the build command `FROM scratch` special cased from now on and if used does not pull/set the the initial layer of the build to the ancient image ID (511136ea..) but instead marks the build as having no base image. The next command in the dockerfile will create an image with a parent image ID of "". This means every image ever can now use one fewer layer! This also makes the image name `scratch` a reserved name by the TagStore. You will not be able to tag an image with this name from now on. If any users currently have an image tagged as `scratch`, they will still be able to use that image, but will not be able to tag a new image with that name. Goodbye '511136ea3c5a64f264b78b5433614aec563103b4d4702f3ba7d4d2698e22c158', it was nice knowing you. Fixes #4242 Docker-DCO-1.1-Signed-off-by: Josh Hawn <josh.hawn@docker.com> (github: jlhawn)
