My really ugly hack to ifconfig to make it pick up interface aliases
and the ethernet address for non-root users. I apologise to the world for propagating the ugliness of some of the code constructs within ifconfig... Fixing them would just abou mean rewriting most of the function call interfaces, something I didn't have the stomach for. :-)
