Do it in the ifcfg-*, and in /etc/udev/rules.d/*-net.rules. I *think*
that's all I've changed.
I have to spoof it on a couple of users' workstations, because they're
running 9 yr old software that's productive... and tied to the MAC address
*and* to the NIC name, so I have to have a couple of parms on the grub2
command line, because it *has* to be named eth0. Oh, and the maker was
sold, and the new company says, "you changed machines? Sure, we'll
generate a new license... that'll be $15,000, please.

Oh, wow, I don't remember hearing about that. What a freakin' pain!
