systemd (220-7) unstable; urgency=medium
The mechanism for providing stable network interface names changed.
Previously they were kept in /etc/udev/rules.d/70-persistent-net.rules
which mapped device MAC addresses to the (arbitrary) name they got when
they first appeared (i. e. mostly at the time of installation). As this
had several problems and is not supported any more, this is deprecated in
favor of the "net.ifnames" mechanism. With this most of your network
interfaces will get location-based names. If you have ifupdown, firewall,
or other configuration that relies on the old names, you need to update
these by Debian 10/Ubuntu 18.04 LTS, and then remove
/etc/udev/rules.d/70-persistent-net.rules. Please see
/usr/share/doc/udev/README.Debian.gz for details about this.
