Kernel (operating system) obsolete by virtually all operating system researchers. As a result, the design of Linux as a monolithic kernel rather than a microkernel was the topic of a famous debate between Linus Torvalds and Andrew Tanenbaum. There is merit on both sides of the argument presented in the Tanenbaum–Torvalds debate. Monolithic kernels are designed to have all of their code in the same address space (kernel space), which some developers argue is necessary to increase the performance of the system. Some developers also maintain that monolithic systems are extremely efficient if well written. The monolithic model tends to be more efficient
Linus Torvalds the issue of church and state separation, Torvalds also said, "Yeah, it's kind of ironic that in many European countries, there is actually a kind of legal binding between the state and the state religion." However, in a story about the March LinuxWorld Conference titled "Linus the Liberator", Torvalds is quoted as saying "There are like two golden rules in life. One is 'Do unto others as you would want them to do unto you.' For some reason, people associate this with Christianity. I'm not a Christian. I'm agnostic. The other rule is 'Be proud of what you do.
