[Cialug] Raspbian (Debian) force eth port

[David Champion]

Doing a dd of the entire 32gb sd card does, but mount it and make a tar
backup, or rsync it will be much faster. Or just backup the changed files,
or the /etc tree will be super fast.

Scenario: you change something that causes the networking to totally break.
Shutdown the Pi, put the sd card in another Linux machine (even another Pi
or the SAME Pi with a usb sd card reader) and mount it, edit the files you
changed back to their original state, put the sd card back into the Pi, and
you're good again. This is super fast and easy.

Again, the ability to experiment and break things without consequence on a
cheap platform is the whole reason that the Pi was invented.
