Actually, it *does* trigger events on carrier change: it creates the
addresses when you connect. It just doesn't delete them when you
disconnect. So you can get addresses without a userspace daemon, but
you can never delete them without a userspace daemon.

I tried to argue that that's incorrect, but, well, the archives show
how far I got.
