Whatever you do, you do need a sane default because even querying the boot protocol is not reliable as the to-be-loaded kernel's boot protocol might be manipulated too, before signing (who knows what people do in the wild). So having a sane, unconditional fallback COMMAND_LINE_SIZE from the first kernel is a must, methinks. -- Regards/Gruss, Boris. Sent from a fat crate under my desk. Formatting is fine. --
