It is possible for a machine to be a master and slave for itself at
the same time.  It's a pretty confusing arrangement though since
processes will show up several times in the process tree.

You can't use the beoboot stuff (MAC addresses and so on) to do this
though.  You will have to run the slave daemon (bpslave) directly.  I
usually set this up on the loop-back interface.  Tell the front end it
is 127.0.0.1.  Then give the slave nodes IPs in the range 127.0.0.2+
Then you can start like this "bpslave -s 127.0.0.2 127.0.0.1 2223".

NOTE: Before doing this, you will want to comment out everything in
the node setup script (/etc/beowulf/node_up) to avoid having the
master try to set itself up.
