Thanks to everyone who responded. This led to some interesting reading and learning, but it hasn’t avoided the reboot.
I found this page on udev: How to reload udev rules without reboot?<http://unix. stackexchange.com/questions/39370/how-to-reload-udev-rules-without-reboot

Sounds perfect for my question, but at least one server I tried all the suggestions on, it didn’t change anything. A reboot is a “magic sauce,” but it’s nice to know how to avoid this with servers. If I find another solution that works for me, I’ll post it.
I learned this to control the MAC address so that the IPv6 suffix for my servers was more to my liking and I could use an RA prefix.

I am trying to understand better how you give an interface a more descriptive name and get it all working without a reboot, if possible.
I actually wrote a small tutorial on how to do just this.

I think you missed the "without a reboot" part. :)
Supposedly you can restart udev and then networkservices

Of course if you don't mind rebooting the system, this will work as well: http://wiki.centos.org/FAQ/CentOS7#head-31ebc6642958a0df12304d6aab9a49034a3b...
