Those udev rules are often a pain when using VM templates. Their purpose is to tie a specific MAC address to an eth# dev, so for example if you configure an IP address for eth0 and then change the mac address (via VM clone or some such), you suddenly have no IP at all, no eth0, and an eth1 tied to the new MAC.
The rule in /etc has the MAC to eth# mappings, and the one in /lib creates the one in /etc. On Apr 18, 2013 9:41 PM, "Chip Childers" <[email protected]> wrote: > > Hey Rohit, > > Can you explain the change below?
