I can think of one server we've got, a Dell PER815, that's got a NIC (that
we don't use, dunno why it was in there), and four onboard.

I disliked it when the first time I started doing sysadmin, on a
Sparcserver 20, back in the mid-nineties, and I don't like it any better
now. Among other things, too easy to mistype one of the letters or
numbers.
About UUIDs, though, I think we can start on that in harmony. UUID is *so*
much easier to remember, and shorter than, say, the serial number on the
disk label... oh, right, it's twice as long....
