to rename nic, I put 70-network.rules to /etc/udev/rules.d/, the content is as following:
SUBSYSTEM=="net", ATTR{address}=="00:18:7D:CC:10:22", NAME="eth0"
SUBSYSTEM=="net", ATTR{address}=="00:18:7D:CC:10:21", NAME="eth1"
then I add etc/udev/rules.d/70-network.rules to .filetool.lst and backup it.
after reboot, I found no it has no effect. I don't know what's wrong, thanks!
