 Thoght of sharing this with u will be handy

I was upgrading my workstation yesterday, only the case and harddisks
remained the same. Almost everything went well, even new init ramdisk
wasn't required, but I was stuck on networking for a while. And the
problem was called "eth0_rename". After querying google it was clear
that this is the result of "network device persistency" feature and
the cause is different MAC address assigned to the new eth0 device.
Solution was easy - remove the old records from

 And add some custom udev mac binding rules like below

 cat /etc/udev/rules.d/10-redhat-custom-net.rules
KERNEL=="eth*", SYSFS{address}=="00:16:3e:66:20:c7", NAME="eth0"
KERNEL=="eth*", SYSFS{address}=="00:16:3e:7e:a1:9c", NAME="eth1"
