AFAIK it's not in the Handbook yet.  The problem is that some network 
interfaces actually take a while to come up after ifconfig is done 
setting them up.  The amount of time taken could depend on the local 
network with autonegotiation and such.

Another approach is to set up the DHCP server--if there is one--to 
assign static addresses based on MAC address.
