A hermetic remote rebuild is when Nixinate sends a specific Nix binary to the remote first, then uses it when activating a system closure, rather than using the Nix that is already on the remote. This is defaulted to false for the time being, as the bandwidth usage can be high. This allows users to avoid the need to bootstrap the remote first by enabling flakes on the remote Nix binary.
