kernel-image-2.6.10-1-686 2.6.10-4 gives the same result:
Feb 10 23:49:46 blabluga net.agent[5662]: Bad NET invocation: $INTERFACE is not

BTW, if you find it usefull, snippet of log with uncommented DEBUG in
/etc/hotplug.d/default/default.hotplug follows:

BTW, if I run an application using tun device (vtund in my case) I noticed
following information in the log:
