The name "service_flags" reminds me on a service:
We connect to a service, but we are not a service.

And "flags" is often used for different bits, collected in an int, but not a "string"

Options are used at the command line, or arguments.
How about "extra_arg", or "extra_option", or "option_str", or simply "options" (or "option") ?

We don't need this "big if" here, a simple "?" will do:
 
			packet_write(fd[1], "%s %s%chost=%s%c%s%c",
				     prog, path, 0, target_host, 0,
				     options ? options : "", /* old service_flasgs */ 
                                     0);
