FTR, Debian/Ubuntu do not use the new schema on upgrades for existing interfaces, just for new installs, for precisely this reason. Specifically, if you already have an existing /etc/udev/rules.d/70-persistent-net.rules, this will still be present (and trump ifnames). But we also disable it for VM upgrades where the previous persistent-net-generator was blacklisted.
