You don't. ifplugd monitors physical interfaces. So why should you tell
ifplugd the mapping?

If there should be some automatism, use guessnet. It does the job.

Why should another package do this?

ifplugd -f
Also, I guess the best solution would be to start an ifplugd for each
network IF by means of hotplug/udev

If some default net is configured, it should be tried. If it isn't,
nothing should happen.

I think, currently it's not possible to specify a fall-back net block
for wpasupplicant (should be an option for future wifiroamd). You also
need a default mapping in /e/n/i, that just tries dhcp. guessnet e.g.
supports such a thing.

Well, what's the problem with just starting it? It doesn't do any
harm, does it?
