Yes, but ... it's legal to say "console=tty,serial".  So perhaps we need
something like ...

	char *constart = strstr(cmdline, "console=");
	if (!constart)
		return;
	constart += 8;
	char *consend = strchr(constart, ' ');
	if (!consend)
		consend = constart + strlen(constart);
	if (!memmem(constart, consend - consline, "serial", 6))
		return;

to examine any refutations of them; and thus he will by and by convince 
himself that the war is just, and will thank God for the better sleep 
he enjoys after this process of grotesque self-deception." -- Mark Twain
