This all works great, EXCEPT that if the machine is booted a fixed-IP profile, the the DHCP ifcfg file also winds up in /etc/sysconfig/network-scripts.  So, if I have in profiles/dhcp/ifcfg-eth0_dhcp (with a hardlink in devices/, of course):

After some fooling around, I figured out that the problem is with the default profile. When you switch profiles, it copies whatever devices are in the profile you switched to AND whatever is in the default profile into .../network-scripts/, and if you delete the default profile or remove all the network devices, it will *repopulate it for you* the next time you switch.  And of course you can't just use the same generic name in all the profiles (ifcfg_eth0), because then it gets really confused since the device names in .../profiles/* have to match the devices in .../devices/.

This is a CHANGE in behavior from CentOS 5, and whoever thought it was a good idea should be forced to use Windows ME for 30 days.
