AFAIK, network devices (NICs) are also managed by udev. Under lenny I have set a couple of rules for them: sm01@stt008:~$ ls -l /etc/udev/rules.d | grep net -rw-r--r-- 1 root root 955 nov 14 2009 70-persistent-net.rules -rw-r--r-- 1 root root 4427 ago 26 2009 75-persistent-net-generator.rules >> I would have thought that something similar happens with an ethernet >> device but I've lost the track to udev development and currently I >> would not put my hand in the fire for what and how it does. > > An ethernet cable is not a device.

It does not have to be an isolated event. For example, the computer is hibernated or suspended, the cable was disonnected, you attach it and then you awake the system that triggers the restore script for the network service and the interface that was marked with "allow-hotplug" cannot be up. There can be another scenarios. Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
