- If set to `true`, Nix will instruct 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 `cache.nixos.org`),
- instead of waiting for this host to upload them all. This can
- drastically reduce build times if the network connection between
