Walnut Creek sold a Sprite CD-ROM back in the day. I got Sprite to boot on a Sun SPARCStation IPC. It was kind of unstable. I really wanted to try process migration and the log structured file system.

Process migration seems like something that should be commonplace today. It would be an amazingly handy feature.

I feel like if you have a single system image, process migration is easy (or at least tractible), but without that, it's going to be pretty challenging. Live migration of VMs across hypervisors is more approachable than migrating a process between two individual systems... You've got all that I/O that needs to be proxied, etc.
Single system image across multiple nodes doesn't seem to be getting much mindshare either.

I did a research SSI in the early 2000s. After getting it largely to work, we kind of put it aside. Why would we aspire to using 'ps' and 'ls' and 'mount' and such to manage our large scale systems? surely there was a better model.
20 years later people are still sshing into nodes to fuss around, and treating cluster nodes like pets. it still could be done pretty easily, I guess its not really in anyone's interest to invest the 2 years it would take. there is a lot more money to be made nibbling around the edges of the problem.
