Surely you mean "Plan9y enough". https://drewdevault.com/2022/11/12/In-praise-of-Plan-9.html shows how he prefers Plan 9 over Unix.

I think he doesn't like the way Unix containers are done, preferring other ways to get them. From that URL:

> Recall that everything really is just a file on Plan 9, unlike Unix. Access to the hardware is provided through normal files, and per-process namespaces do not require special permissions to modify mountpoints. Making a container is thus trivial: just unmount all of the hardware you don’t want the sandboxed program to have access to. Done. You don’t even have to be root.

Where does he express a dislike for the concept of containers? After all, he's working on a new microkernel OS, with a permissions model that seem designed to make containers easy to implement.
