hello, sounds like it may help in the future, though my only networking card, (wireless or otherwise) is just ethernet, so not sure why it got renamed. ----- Original Message ----- From: "Kerry Hoath" <kerry@xxxxxxxxx> To: "Speakup is a screen review system for Linux." <speakup at braille.uwo.ca> Sent: Wednesday, February 25, 2009 9:37 PM Subject: Re: eth0 not recognized:school system > You might experience trouble eventually from obliterating udev, it seems > to be becoming more and more ingrained and it solves a lot of problems as > well as creating some interesting situations. > I think hotplug is deprecated not sure. > There is a good reason for the eth0 funnies, both why interfaces are > renamed and why they are locked in place. > On a normal box you don't usually want a firewire interface showing up as > eth0, as the average user doesn't want to network with firewire. > > Also on a normal box when you boot the kernel without the udev magic > multiple ethernet interfaces are detected in the order the kernel finds > them.
