why *install* at all?  so far at least, I'm booting my new cluster
entirely diskless.  each node actually has a disk, but nothing is 
installed on it - everything is PXE and NFS.  obviously, this is 
more network-intensive, but is it really an issue if your jobs last
for more than a couple minutes?

is that really true?  great if so!  I haven't looked, but tend to only
expect builtin eth to support PXE...

dhcpd can allocate IPs from a pool; if you don't need stable IPs,
you don't need to collect the MAC...
