The funny thing is, that it doesn't for me.

If you conpare the trace I sent and the one that Artur sent
we see this difference

Feb 11 00:12:42 blabluga udev[6599]: configured rule in '/etc/udev/rules.d/udev.rules[98]' applied, 'tun' becomes 'net/%k'

I checked and I don't have /etc/udev/rules.d/udev.rules on my system,
but it seems to me that it is this file that is making the translation
from misc to net. And it is this translation that I am wondering
about the validity of.

To explain in other words. When /sbin/hotplug is called by the kernel
it is called for a misc device. Somewhere in userspace
(/etc/udev/rules.d/udev.rules) this is changed to a tun device.
It seems that this change is causing the warning. That is
a change in userspace, interpretated by another part of userspace.
It doesn't sound much like a kernel problem to me.

And in any case, I ask again, is there a bug other than
a spurious debug line logged somewhere?
