Just to clarify: net.ifnames=0 disables the systemd/udev interface renaming feature. biosdevname=0 disables the biosdevname interface renaming feature, which is completely separate. If you want the traditional, non-deterministic Linux interface naming, you must specify both. Also, if you add rules to /etc/udev/rules.d, you should rebuild your initrd.
