This adds a new `imageStream` option that can be used in conjunction with `pkgs.dockerTools.streamLayeredImage` so that the image archive never needs to be materialized in the `/nix/store`. This greatly improves the disk utilization for systems that use container images built using Nix because they only need to store image layers instead of the full image. Additionally, when deploying the new system and only new layers need to be built/copied.
