I unconscienciously wrote my previous post with static addressing (which
is what is on this machine for some connections) in mind. However, the
thrust of it is still correct: booting with the ethernet cable attached
gives you two operative interfaces and can lead to some messing about to
get just one in action.

The -C option is being used incorrectly.

Ok if you are not using ifplugd. Lose the first line if you are.

Pass on this.

Ok, but will need altering if roaming is in place.
A word about 'wpa-driver wext'. The supplicant takes care of choosing
the driver. On Squeeze the order is wext, nl80211. On testing and
unstable it is nl80211, wext. The line could be superfluous.

You want to manage the interfaces by connecting and disconnecting the
ethernet cable. Disconnecting causes wpa_supplicant to bring eth1 up,
See /etc/wpa_supplicant/action_wpa.sh.
