Does showmount ever forget?

Err, I don't think I said that file *should* be cleaned up on reboot. 
The reason I didn't say that is that the fact that a *server* reboots
doesn't directly change what file systems its *clients* have mounted. 
As such, "/etc/rmtab" is *not* one of the files that "should be but
[isn't] removed on restart"....

If you ream "/etc/rmtab" out on reboot, you might as well just try
symlinking it to "/dev/null" and be done with it; that'll keep the
server from ever sending out those broadcast messages, but some might
consider that a feature....
