Background: I have two little Linux boards (Arietta G25) with a RT5370 Wireless Adapter each. I want to make both able to communicate with each other beside being able to use the ethernet-over-USB connection to enable the communication with/to my PC Usually it's better to answer to question and not challenge the original goals of the poster. Despite of that I want to ask why you need WiFi? Why not just route the traffic from one arietta to the other through the usb? Arietta A eth0 - usb - pc - usb - Arietta B eth0 A lot easier setup.

Doesn't that create more CPU load than passing the port? And at some point, you may saturate the bandwidth of the port. But it's your server, you decide on the complexity. I stopped passing physical NICs when I was encountering issues with newer cards. They are now resolved, but passing virtual interfaces is simpler and more reliable. The only issue I have with passing the port is that the kernel module must not be loaded from the initrd image. So I don't see how fighting with the bridges would make things easier. -- Again we must be afraid of speaking of daemons for fear that daemons might swallow us. Finally, this fear has become reasonable.

Building a liveUSB version of Gentoo is almost completely orthagonal to building an automatic ebuild testing system. Agreed from where you sit. Where I sit, when I explain to folks about this project, a liveUSB stick running the latest in what gentoo-fever is, speaks volumes to encourage non-gentoo folks to take it for a test drive. I didn't say it was a bad idea. I just said that it had nothing to do with Continuous Integration (CI). If a billion people used Gentoo for 8 hours a day straight, that would also have nothing to do with CI. A Gentoo CI system doesn't even have to be hosted on Gentoo, or on Linux for that matter. Of course, if one were ever to become official it most likely would be hosted on Gentoo, but most likely not on a box booted from a USB. Um, I never saw CI defined, so please define specifically, then use the abbrev? Continuous Integration is probably being used a bit loosely here. The concept is testing every commit to ensure a level of quality. Commits wouldn't directly hit users - they would be tested first (perhaps in batches), and then would only hit users if they pass. Or something along those lines. Maybe it would just refer to frequently testing the tree with automated bug reporting. None of this has to do with having a USB live distro. Well the same kind of minimal core is useful/needed as the 'base' from which ebuild test runs can be done on top of. So its not a completely orthogonal problem. I'm not saying that a liveUSB version of Gentoo wouldn't be nice to have. It just has nothing to do with solving this particular problem. OK, see above; you are right technically. Do you want a few dozen participates or a few thousand? I want ZERO participants. That's the whole point. It is supposed to be automated. Sure, somebody has to write the code, but I doubt handing out liveUSB images is going to inspire that. Also, if your main goal was to have a quick easy-to-use Linux desktop, I'm not quite sure why you'd pick Gentoo in particular to base it on. The whole point of Gentoo is that you can change it, while a liveUSB tends to imply something static and standardized. Heck, they could use ChromeOS as it is a Gentoo derivative. However, if you want something in-between Sabayon is probably about right. :) Gentoo is actually capable of everything that draws people to Arch Linux. The only reason anyone ever gives me for using Arch Linux is the AUR which is pretty much 'portage plus layman for dummies'. So Gentoo does have the ability to give people what they want, we just have no way to support that kind of use case at present. I agree a live USB image wont really 'inspire' anything. But it does represent a useful goal. The same infrastructure that tests ebuilds would be able to generate boot-able images. You may not have been far off the mark with ChromeOS, I think it may be possible to use those tools to build an image without much fuss at all. I would need to remove a fair number of ChromeOS and CoreOS parts from the setup I currently have but it should in theory work fairly easily. But other than improving the process of building a base image, it doesn't really get us anywhere closer to the goal of automation and CI. Rich, you mentioned zero participants and your right on the money, which is why I'm still wondering where people want to collaborate on this effort. Working code and projects is nice but having things spread over several projects doesn't help keep things easy to manage or deal with discussions about how we integrate things together. For instance at some point this should integrate into the ebuild arch unstable masking for all of Gentoo and then things get 'political'.
