@ebits21 @Fbartels #Silverblue should replace #Toolbx with #Distrobox. Toolbx was first they had the idea, but now it is only inferior. I think Toolbx devolopers should abandon their project and just start to work on Distrobox.
I also agree that Silverblue should become fully declarative so that we can rebuild it with all layered packages, distroboxes, and flatpaks.
