I've tried just about every method you can think of to get this to work correctly.
Unfortunately, passwd is coded to only accept from a tty. The only thing I could think of
to get it to work is to create a pseudo tty (pty) and use that to send input to the passwd
program. I have no idea how to do this, though. There may also be an easier way.
