The easiest way would probably be to disable the fast ethernet device so 
that the startup process for Rocks assigns eth0 to the gigabit 
interface.  The interface assignments on the frontend can be changed 
easily after the install process via reordering the interfaces in the 
/etc/modules.conf file (beware of any HWADDR lines in the 

All of this does of course assume that you will be putting *all* traffic 
over the gigabit network.  It is very possible to separate different 
types of traffic over two networks (say, save the gigabit for MPI traffic.)
