7.4.1.1. Disabling Persistent Naming on the Kernel Command Line
The traditional naming scheme using eth0, eth1, etc can be restored by adding net.ifnames=0 on the kernel command line. This is most appropriate for those systems that have only one ethernet device of the same type. Laptops often have multiple ethernet connections that are named eth0 and wlan0 and are also candidates for this method. The command line is passed in the GRUB configuration file. See Section 8.4.4, “Creating the GRUB Configuration File”.
