While you can create your own version of a KDE image-mode operating system based on bootc in various ways, I think it would be easier and more beneficial for the community and the project to use the already available bootable container image that I mentioned in my previous post.
Anyhow I’m not a member of the Fedora Magazine team and my opinion probably won’t matter, but I think any article about Fedora image-mode operating systems in general would be interesting.
