I figured this out now.  I was quite confused.  I see now you want each
device to have a unique, but consistent mac address, to make linux recognize
them on each boot.  When you don't specify a mac address in the colinux
conf, it assigns one at random, and udev then thinks they're new devices and
assigns them a new eth#.
