One could look at the current box, with its non-library file system, and see a strong resemblance to the directory names of a Unix system - /etc, /usr, /dev, /home and all that.

But all this came when IBM added the IFS much late in its life cycle.

Definitely not. If you've worked on the platform over the years, you would see the evolution from the System/3x through the AS/400 and on to the i - no Unix at all in the early years. One of the surest arguments for a non-Unix pedigree is the lack of a hierarchical file system - an absolute requirement for Unix - in the original architecture.
