There’s an installation option to run apps off disk. It’s called “The Mount Mode of Operation: TCE/Install”.

To think that the entire distro would fit in a reasonable LLC (last level cache)..

I've been wondering if I could pull the DIMM from a running machine if everything was cached.

Probably not due to DMA buffers. Maybe a headless machine.

But would be funny to see.

Like the k language!
