Rename network interface back to old "eth0" on Fedora/RHEL/CentOS

The easiest way to restore the old way Kernel/modules/udev rename your ethernet interfaces is supplying these kernel parameters to Fedora 19:

net.ifnames=0
biosdevname=0


To do so follow this steps:

1. Edit /etc/default/grub
2. At the end of GRUB_CMDLINE_LINUX line append "net.ifnames=0 biosdevname=0"
3. Save the file
4. Type "grub2-mkconfig -o /boot/grub2/grub.cfg"
5. Type "reboot"

If you didn't supply these parameters during the installation, you will probably need to adjust and/or rename interface files at /etc/sysconfig/network-scripts/ifcfg-*.
