It's very simple for me...you don't support my OS, I don't support your network or problem.
I had Time Warner / Brighthouse Networks come to my home for cable internet installation and the guy asked where my PC was so I showed him and then he said he had to run a set up CD. I looked at the guy like he was crazy
I thought to myself this would be funny so I showed him to my PC loaded with Debian Etch AMD64 and logged in for him. He sat down and grabbed the mouse and attempted to look for the "Start" button.
Aw man - it was classic. His response was "Oh, is this a MAC"...
I laughed and told him he could leave the CD with me however I was able to sit down and ifdown eth0 and ifup eth0 with no problems.
