Disable ethernet device renaming upon system cloning for Linux

1. Specify static address in prototype system

modify /etc/network/interfaces

auto lo eth0iface lo inet loopbackiface eth0 inet static address 172.19.10.11 netmask 255.255.255.0 gateway 172.19.10.1

2. Clear out already stored MAC-name mappings

modify

Debian 4: /etc/udev/rules.d/z25_persistent-net.rules

Ubuntu  : /etc/udev/rules.d/70-persistent-net.rules

delete all lines like

SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:19:21:fe:26:49", NAME="eth0"

 

3. Disable renaming at all

modify

Debian 4: /etc/udev/rules.d/z45_persistent-net-generator.rules

Ubuntu  : /etc/udev/rules.d/75-persistent-net-generator.rules

find

ACTION=="add", SUBSYSTEM=="net", KERNEL=="eth*|ath*|wlan*|ra*|sta*"

delete "eth*|" part from it as

ACTION=="add", SUBSYSTEM=="net", KERNEL=="ath*|wlan*|ra*|sta*"

 

That would be all for Debian / Ubuntu 810. Have no CentOS / RHs on hand so please add me if you have such systems.
