When set, nixos-rebuild will add <option>--use-substitutes</option>
to each invocation of nix-copy-closure. This will only affect the
behavior of nixos-rebuild if <option>--target-host</option> or
<option>--build-host</option> is also set. This is useful when
the target-host connection to cache.nixos.org is faster than the
connection between hosts.
