renaming feature, which is completely separate. If you want the
traditional, non-deterministic Linux interface naming, you must specify
both.
You call it "deterministic". I will note that it is, in fact, straight
from Sun - 20 years ago, that was the naming on the Sparc Server that I
first picked up sysadmin work. Which was fine... FOR SUN HARDWARE. For
admins and users, it's *really* NOT a great idea, given that the system
could have a m/b from any OEM, and even trying to set up a std. kickstart
is a pain with that, much less anything more arcane. Why ethx, with the
option of adding the firmware MAC address, is such a bad idea, I have no
clue.

?!?!?!?! THAT I had never considered, nor done, and I'm sure that in
CentOS 6, I've changed things there, and just rebooted. Oh, great, I'm
getting flashes of WinDoze.
Thanks for that info, though. I need to remember that.
