Okay so I figured that out.  As you said I just uncommented the line
/net /auto.net
in /etc/auto.master

and then  something like
ls /net/frodo

mounted all the exports on frodo to corresponding mountpoints in /net/frodo

So, I guess my next question is with this setup, how do I umount them,
or at least make sure that they are flushed if I shutdown or reboot,
or is this somehow done automagically?
