Mostly it worked. But I had to put HOTPLUG_INTERFACES="eth0" in /etc/default/ifplugd to prevent boot process from hanging while startin the mta. If I left HOTPLUG_INTERFACES="", during the boot process the computer hangs at: Starting MTA: and I have to manually reset the laptop. I have the laptop working on two networks at home (one static the other dhcp). I will test the laptop in my university in a day or two.
