possible to rm a container that is being used by other containers via -volumes-from #3634
Description
When this occurs it renders the child container unusable unless one commits the container's image and runs a new container from it without -volumes-from.
$ docker run -v /mnt/vol -name data_container busybox touch /mnt/vol/base
$ docker run -name child -i -volumes-from data_container ubuntu ls -al /mnt{/vol,}
