remote build machines to use their own binary substitutes if available. In

practical terms, this means that remote hosts will fetch as many build

dependencies as possible from their own substitutes (e.g, from

<literal>cache.nixos.org</literal>), instead of waiting for this host to

upload them all. This can drastically reduce build times if the network
