kickstart install using NFS

[Yudong Tian]

It happens that I just did PXE a couple months ago and jotted down the procedure 
I took, in fairly detail,
   http://hsb.gsfc.nasa.gov/yudong/notes/net-install.txt

It took ~5 min for a node to get done, and you can do it in parallel with many nodes.
A floppy would not have been used if we had not had to update the BIOS
for other reasons.
