You gave him an excellent answer. I hope many people read it. He should just read the Unix paper I mentioned in other post. Not the multiusersystem is a burden, bloat in modern unixoiudes. It is a very simple and usefull concept.
A prime example of a "single user" system according to your definition is MSDOS. No restrictions on anything. How reliable is/was it?
Well, that was not a good example. As far as I know, DOS was not multitasking. If there may be many processes, then the idea of classifying and restricting them follows immediately. But what is the cause of this confussion? Most desktop systems, the ones that perhaps the OP has in mind, are a big confuse bloat, so that the simple unix idea is difficult to recognize in them.
