Comment 21 for bug 1467640

Right, that was my concern -- the ofono package could ship that /lib/systemd/network/00-rmnet-kernel.link without the need for any overrides during image build or device tarballs. You would need the latter if you want to disable persistant names wholesale.

If you want to disable it wholesale, then either boot with "net.ifnames=0" on the kernel command line, or create an empty /etc/udev/rules.d/80-net-setup-link.rules to override the rules in /lib/udev/rules.d/.
