Bug#340935: Netcfg - hotplugging config no longer works with 2.6.14 + udev

Hotplug itself was modified to use the "allow" mechanism.

    hotplug (0.0.20040329-25) unstable; urgency=low
    ...
     * NET_AGENT_POLICY is deprecated. use ifupdown "allow" mechanism instead.
       closes: Bug#303383

So, it should suffice if netcfg is modified to write /etc/network/interfaces
that employ the new "allow" mechanism, in the manner you suggested.
