The idea actually came from Dell. It's frequently described as a method to prevent the device name from changing during a reboot, but that was already in place. What biosdevname does is make names *predictable* on Dell systems. It shouldn't be enabled anywhere else. As you stated, the documented method of turning the feature off is to add biosdevname=0 to the boot configuration (which means rebooting). http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming
