I'm not exactly sure what Jack means here, but a diskless client must be
set up to *either* swap to the server or to local disk(s).  This is set
in the kernel configuration file that is used to create the kernel.  In
the case of a cnode, the swap site must also be indicated in the
clusterconf entry for that cnode.  Processes running on a cnode will
swap to the root server's swap or local swap, but not both!

Now, it is possible to start a process that displays on your
workstation, but runs on the root server, and thus utilizes the root
server's swap that way.  I don't think that's what Jack meant, though.
