That sounds great! Would you mind making the image available with some installation instructions? Is it possible to revert to the default Edison firmware after this? The default flashing procedure asks you to upload the firmware files onto the mass storage that Edison creates when connected via USB, I'm assuming that no longer works when running Debian.
Also, some Android distributions allow you to run Debian under chroot (using the Android kernel), I wonder if this would work on the Edison as well. This would not require a reflash, it would run side by side with the original distribution. Has anyone tried this?
