Runsc, huh? Sounds like a new superhero in town, ready to save the day from... I don't know, containerized supervillains?

Hmm, the 'not-trusted' runtime, eh? I wonder what kind of shenanigans that one gets up to. Hopefully it doesn't try to hack the master node while we're not looking!

Wait, we have to create a RuntimeClass now? I thought the good old 'docker run' was simpler, but I guess we're in the future now.

Yes, I agree. We can update all Pods in the namespace server to run on the new runtime after creating the RuntimeClass.

I think the task is clear, we need to create a RuntimeClass named not-trusted using runsc handler.
