[CentOS] Kickstart ksdevice question

Hello,

ksdevice specifies which NIC to be used during the network install.

The new naming conventions indeed make this more complicated than it needs to
be. To go back to the old naming scheme (eth0, eth1 ...) just add this to boot
parameters (kernel cmdline):
biosdevname=0 net.ifnames=0
