Description Martin Wegner 2004-06-27 01:23:45 UTC

I've activated

Device Drivers  --->
 Networking support  --->
  <*>   Universal TUN/TAP device driver support

im my 2.6.7 kernel. When udev starts after the kernel it says "add event not handled". When I add the output of $INTERFACE in /etc/hotplug/net.agent where "add event not handled" occurs, I see "add /dev/net/tun event not handled" when booting. It is obvious why this is not handled since the cases in net.agent only handle tun* but not /dev/net/tun . So I guess there should be no path /dev/net/ in /dev/net/tun .
This seems to have no appreciable effect on using openvpn, for example.

Reproducible: Always
Steps to Reproduce:
1. Activate "Universal TUN/TAP device driver support" in kernel config
2. Compile kernel, ...
3. Reboot
Actual Results:  
Message "add event not handled"

Expected Results:  
No message

Who prints out that message?  The hotplug system?

This is to be expected, the network startup should not handle the tun device.

I don't see the problem here.

I just thought since something seems to be missing ("add event not handled") that I should report it. If it's expected, ok ...
