/dev/urandom

Yeah, there's the chance of clashes. In practice there won't be any clashes,
however. If you think there's a real risk, you should start playing
the lottery tomorrow. You'll immediately win a million dollars so you don't have
to worry about those questions anymore. ;)

In fact, I think the risk for mac clashes is not really reduced by generating the mac
address from serial numbers, whatever, etc...
