Unix is nothing to do with Linux and Unix was about creating a beautiful system not by having a huge crap filled kernel, but by having only the minimum necessary in the kernel. Unix was not about what was put in but what was left out. "We used to sit around in the Unix Room saying, 'What can we throw out? Why is there this option?" - Doug McIlroy GPS is a train wreck for commonality. Most GPS requires custom binary only user space code often obfuscated in order to meet the regulations governing GPS technology to stop third parties using it for missile guidance.
