The pass() function that does the prompting is still in
/sys/src/cmd/init.c, but the call seems to have vanished.  I guess I
best look in old sources for it...

Here is what it used to look like:

for(;;){
	if(iscpu){
		consctl = open("#c/consctl", OWRITE);
		key = open("#c/key", OREAD);
		if(consctl<0 || key<0 || write(consctl, "rawon", 5) != 5)
			print("init: can't check password; insecure\n");
		else{
			pass(key);
			write(consctl, "rawoff", 6);
		}
		close(consctl);
		close(key);
	}
	print("\ninit: starting /bin/rc\n");
	fexec(rcexec);
	manual = 1;
	cmd = 0;
	sleep(1000);
}

And here is the new one:

for(;;){
	print("\ninit: starting /bin/rc\n");
	fexec(rcexec);
	manual = 1;
	cmd = 0;
	sleep(1000);
}

I always regretted losing this bit.
