Well, we're now more than a week after but I got some extras with actual container images and a blog post with all the details: https://gtucker.io/posts/2024-09-30-korg-containers/ In a nutshell, this went down rather well at Plumbers. I think there are still a few critical points to address before bringing this up as actual RFC kernel patches but let's see how this goes. Many thanks once again to the Toolchain Track organizers and Nathan for the feedback. Best wishes, Guillaume
