Even with static ip configuration, It is good too specify mac addr in 
regard to udev enabled dsiributions. If mac is not specified you 'll end 
up with a different mac address at each boot boot and udev will then 
create a new NIC each time, your entwork card being eth0, then eth1, 
then eth2 and so on...
