(please PLEASE trim quoted articles to just what you're commenting on,

I've /never/ seen RHEL/CentOS or any of its predecessors renumber
ethernet ports on a working system.. I've seen it number them
backwards, such that eth0 was the port labeled '1' outside the chassis
and eth1 was port '0', but it was extremely consistent about this (one
specific case of this I remember is RHEL2.1 or 3 on a Intel SE7501WV2
dual xeon board). I've had a pile of different RH linux configurations
running on various servers for 10 or more years.
The behavior changed when the system started using udev. Devices are
detected in parallel in more or less random order now. However, the MAC
address of each NIC is normally stored in the corresponding
/etc/sysconfig/network.scripts/ifcfg-ethxx file and they are renamed to
match the device specified in the files as they are activated.
Kickstarting is a special case since these files don't exist yet, but
you can specify ksdevice either by mac address or as bootif, meaning the
interface where the pxe boot happened, according to:
