As much as I like the idea of enabling Debian on Edison - and that's something I'm going to participate in to make it even easier to use in addition to all that great work done in the Debian thread - I think Yocto is here to stay, so the matter of adding functionality and utilities to the default image is going to be actual for a while. I personally also see a point in having Yocto as an option, as it allows you to create a very focused and trimmed down image for your specific project (after you're done with experimenting and developing, where flexibility in juggling the libs and packages is a key), avoiding the bloat coming with the "general-purpose" distribution.
So in the manner similar to Galileo I've created a package repo for Edison. All the configuration information is on this page and it's as simple as editing one file on the board. The repo hosted on the same site as the Galileo's and big thanks goes again to Daveman for providing that
The repo is based on my own build of the OS image out of the currently released BSP, which adds several items like uvcvideo, gspca_pac207 and ftdi_sio modules as well as the latest Node.js, Motion and some other utilities on top of that. It's the one I used in my demo project. I'm going to publish the image as well a bit later, but with the repo you pretty much should be able to add the necessary stuff to the official image (I haven't tested that, but should be possible). Uvcvideo would require kernel reinstall as it's a bit more than just a module in this case, but still looks possible theoretically.
Feel free to check it out and post your feedback as well as wishlists in this thread, I'll try to add the packages as the time and resources permit. Just to make it clear - while I do work for Intel as my forum name implies, I'm not in the Galileo or Edison development or support teams and this repo and other work I do for Galileo and Edison is my hobby (though developing over time into something more serious ) and I'm running this in my free time.
