https://github.com/pytest-dev/execnet/blob/3ea8374724f436a3a73ffc2e481d
c2a66b208a97/execnet/gateway_io.py#L92-L104 generates the command

https://github.com/pytest-dev/execnet/blob/3ea8374724f436a3a73ffc2e481d
c2a66b208a97/execnet/gateway_io.py#L123-L136 puts it together with
initializing the server
