Ah, I see. The udev.postinst script is hardware dependent and evaluated
only once at upgrade time, breaking dpkg-reconfigure.

The system in question is a bootable USB stick, supposed to run on all
my hardware. I boot it in kvm only for maintenance (e.g. for the
upgrade). This time the upgrade was done on a real laptop and booted
in kvm later.

Wouldn't it be more reasonable to add this virtio specific code
unconditionally? There might be 2 or more real or virtual network
interfaces at upgrade time, e.g. both e1000 and virtio. This
shouldn't affect the outcome.

My suggestion would be to add a debconf dialog to enable/disable
the "network renaming code" (independent from the network interface
driver). Using dpkg-reconfigure we would have the usual config
interface for this feature, giving everybody a way to choose and
to change later.

I don't see why this is a different case. Using kvm the e1000 is as
virtual as the virtio interface. And its affected by the same broken
network configuration after the udev upgrade.
