I want to be able to create a ethernet device without assigning an IP and without modifying the routing table. I need this for a eth-device connected to a DSL-modem using PPPoE. The reason I don't want to use a fake IP is that I'm going to distribute this configuration and don't know if the IP / Network I've chosen is really bogus in the context of all users. I've made a patch against initscripts 5.49 which adds a device without IP if the IPADDR var in ifcfg-ethx is empty.
Created attachment 7709 [details] This patch implements it
Request seconded. I have the same situation and had to trick around, too.
A slightly different version is added in 5.60-1 - thanks for the patch.
