I am confused. In what sense of the phrase is this an operating system?

It says things like "Node is the primary runtime---no bash here" which to me betrays a misunderstanding of programming and operating systems on multiple levels. Bash is not a "runtime" or part of the operating system, it's a simple user-level program for managing jobs and navigating your filesystem.

The diagram of "where Node OS lives" points to a layer between kernel and userlevel called "root". What exactly does this mean? Root is a privileged user, not a layer.

Finally, "The primary goal of NodeOS is to provide a working package manager." That is unequivocally not what an operating system is.

If it's a package manager written in Node.js -- fine. If it's a shell written in Node.js -- fine. But from what I can tell, "Node OS" seems to be a misnomer.
