We could just allow arbitrary options to be set by the server. It might break cases where the server just passes unknown options down into the kernel, which currently are rejected. I don't think this is common practice, but still it sounds a bit risky. Alternatively allow INIT_REPLY to set up misc options, which can only be done explicitly, so no risk there. Thanks, Miklos
