To summarize: it keeps the real or virtual system from having to 
initially DHCP when enough information is
stored in Cobbler (or can be found on the local system) so that it's not 
required.    Depending on the kickstarts
employed, the kickstart may still indicate a DHCP configuration, so this 
would only save the initial DHCP.

Did I get that right?

For clarification, Cobbler 0.6.3 is relevant because each NIC has an 
optional --gateway and --subnet parameter, where
before there's not as clean of a way to save/access that information 
(--ksmeta).
