OSNews, Generic OSes Torvalds has indeed chimed in on the micro vs. monolithic kernel debate. Going all 1992, he says: "The whole 'microkernels are simpler' argument is just bull, and it is clearly shown to be bull by the fact that whenever you compare the speed of development of a microkernel and a traditional kernel, the traditional kernel wins. The whole argument that microkernels are somehow 'more secure' or 'more stable' is also total crap. The fact that each individual piece is simple and secure does not make the aggregate either simple or secure. And the argument that you can 'just reload' a failed service and not take the whole system down is equally flawed." My take: While I am not qualified to reply to Linus, there is one thing I want to say: just because it is difficult to program, does not make it the worse design.

The most important library in AmigaOS is exec.library, which is actually a microkernel as well as a library. As well as pre-emptive multi-tasking and access to other libraries, it provides high-level inter-process communication via message passing.

Indeed, but beeing more exact they should have said that Amiga Operating System is a hybrid mixing two ideas: of a microkernel and of an exokernel.

The AmigaOS was very slick how ever the hardware and 680x0 CPUs and motherboard chips at that time rather limited in supporting this elegant design.

How about the new Amiga OS 4, will this extend the OS and maintain it as a microkernel / exokernel ?
