this really belongs in comp.os.silly-questions, but here goes anyway ...

is unix REALLY a multi-user operating system?  or does it just act that
way because it is a multi-tasking o/s?  i know most of the actual history
behind unix, and i recall reading once that dennis didn't consider unix
to even be an operating system.

so, what features does unix have which prevents it from being a single
user operating system with a very clever single user program (init)
running?
