Do you mean like Docker has supported for years…? (Just configure krun as Docker's OCI runtime.)

Obviously, there's a reason why Docker released Docker Sandbox as a separate product:

- Barely anyone bothers to configure Docker/Podman with a different OCI runtime like krun. Heck, most people don't even know about OCI runtimes in the first place. Case in point: Most people here in this HN discussion are proposing using "standard" containers (with the default OCI runtime) for sandboxing. This is what I was trying to get at.

- A sandbox for agent needs tighter network control.
