In a typical situation we do not remove the rootfs img and don’t recommend removing it as it’s better cached by Docker, if you wish to delete it we will. Now, here we only remove it if we get told to exit, since we will be in the middle of a build and probably not have tagged yet, unless we are downstream, we will remove it so you have no broken images on your system.
