Don't touch udev, expecting admins to write udev rules for network interface binding is just not realistic. Udev rules are meant to be static across hardware reconfigurations while ifcfg files are meant to be modified to suit your current configuration.
Use HWADDR="00:1b:21:4d:c3:e8" in the ifcfg files along with NAME=eth0 for eth0 and so on.
I read a while ago that udev overrode ifcfg-* settings so I did a clean install of 5.4 and changed: ifcfg-eth0 to ifcfg-eth9 (file name) eth0 to eth9 (inside the file) the last number of the HWADDR line
Do you mean that you changed the HWADDR line so it no longer matched the actual nic mac address? In that case, you shouldn't expect it to work.
The nic came up as eth0 with the old/original mac address after a reboot.
So we unfortunately have to write udev rules when we have nic naming problems...
I think the ifcfg-eth? files work when they match the nic mac addresses. They may have to all match for any of them to work, though. I've seen some cases where they all get renamed with a .bak extension and new ones are created but I don't know what triggers that.
Usually a new kernel that forces a regeneration of the hwconf.
There was a kernel update maybe the move from C4 to C5 which caused grief with Dell hardware, where it reversed the order Broadcom devices are detected, still does and needs manual swapping around after install.
