"Personally, I'm _not_ interested in making device drivers look like user-level. They aren't, they shouldn't be, and microkernels are just stupid."

— Linus Torvalds


Linus probably said that in 1994. The cpus have become much stronger and the linux kernel's value as a component now outweighs its ability to do fast tlb and cache flushes on its own. So running everything monolithically with a single kernel is not that relevant anymore.

That is why Liedtke's work led directly to what I think was one of the most exciting OS projects of the late 1990's - IBM's Sawmill project, an attempt to break up the Linux kernel services to run as components on L4.

Does anyone know why Sawmill died? It conincided with Liedtke's death, but I don't know if that was a major factor.

And Linus can never be wrong? Right?
