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.
