I found the Linux Landlock feature last night and thought it had several usecases in the container/k8s ecosystem. I then ended up finding a presentation from one of the maintainers that validated my assumptions. I quickly just started putting some code together to see what this would look like since the current approach requires a code change to the application and I wanted to see if its possible to do this transparently to the process down in the oci runtime layer. A lot of other steps need to go into this obviously such as a specification proposal. By no means is this final or even working. Its just to start a conversation.
