And if I have a 5-yr-old Penguin (OEM-branded Supermicro), and a Dell
PowerEdge R530 and an HP ProLiant dl580 and a hot-off-the-presses

As opposed to you installing a new NIC in addition to one that's there...
which, since you've just installed it, I suppose you could add the UUID to
whatever you want to name it.
