The problem with doing a DHCP afterwards is that I don't know which NIC
to do the DHCP on - that is if I want to DHCP on the same NIC that was
used to PXE.

The main purpose for the ramdisk is to install OS "images" to the
machine - so what I will probably end up doing is cycling through the
interfaces doing a DHCP on each and attempt to contact the "image
server" using a broadcast (or something).  The only issue with that (and
why I like the idea of using IPAPPEND) is because doing the DHCP request
for each interface can be a slow process.

I really like the idea of passing MAC=<mac_address> and then finding the
matching interface in the ramdisk though.
