[Discuss] environment variables in debian

[pw]

Thanks Noel,

That's exactly what I needed.
Everything works great now.

I wasn't sure how the driver could possibly use an
environment variable without running a shell.

I figured, in this day and age, there must be a GUI
or something for setting this up. I guess not.

Thanks again,

Peter
