I think the mount succeeded because no one was required to send more than 8K at once. IIRC A was BSD/OS 4.x, B was Linux 2.4.x. Man, that was a weird bug. Took me *days* to pin down, because it would mysteriously disappear as long as you only dealt with files < 8K. Which as it turns out is almost all of them except the password file. Lee
