That's exactly how I do it.  Then, in the Kickstart configuration script,
I have the node configure itself not to use DHCP anymore.  It is a bit
cumbersome when new nodes are added, but since the nodes that I will be
installing in two weeks are the product of a purchase cycle that started
in February, I don't have to worry about doing it too often.
