How is EROS related to Linux or other UNIX systems?
Short Answer: It isn’t. Longer Answer: EROS and UNIX-derivatives come from very different schools about how operating systems should work. For starters, Dennis Ritchie and Ken Thomson (who built the first UNIX system) set out in the second and subsequent versions of UNIX to build an operating system that would provide compatibility across multiple platforms. With considerable success, they build a system that provides a common source-level environment across many types of machines. They accomplished this at a time when things as basic as the size of a byte were not universally agreed on. UNIX borrowed ideas heavily from MIT’s Compatible Time Sharing System (CTSS) and also from Multics. From these places came such ideas as files and directories, user identities, and binary executable files. Each of these ideas, over the years, has proven to be a source of security challenges or flaws in the system. Where UNIX descends from CTSS and Multics, EROS descends from KeyKOS (Key Logic, Inc.), w
