Bug#248071: Hot plugged devices shouldn't be marked "auto"

I agree. But how do we provide a smooth upgrade here? Default to the
new behaviour on new installations but ask using debconf during
upgrades from earlier versions with the old behaviour?

It already does (barring bugs), but I see in another mail that you
already know that.

The installer only configures one interface (except lo).

I thought that this was difficult previously but now I know that one
can simply look in /var/run/stab to determine whether a network
interface is a 16-bit card (Cardbus interfaces aren't listed). So
implementing this in hw-detect should as simple as changing one line
in the gen_pcmcia_devnames function in hw-detect.sh. Changing this in
netcfg should be simple as well.

This solution would be preferable, but is it feasible to make this
change for sarge?

I agree that this is ugly, but is it a problem in practice?
