Linux/MINIX (Score 2)

I'm currently taking an operating systems course in my 2nd year at university. The course uses MINIX as its example operating system. This includes using examples of how MINIX implements, say handling concurrent processes, in the leactures and also using MINIX as a base for the practical work in the course, although we don't actually fiddle with the MINIX code itself. I think that whatever OS you use in an OS course it is important to remeber that just studying that OS will not give a rounded a view of how OS's work. Rather the implementation of the OS studyed should be used as a getting off point to also look at the many alternative ways in which OS features can be implemented.
