Meaning of CSS units

Is the meaning of CSS units defined by the user space or the viewport
space?

I think they are defined by the viewport space.  7.7 says "the various
absolute unit specifiers...represent lengths within the initial user
coordinate system".  The initial user coordinate system is not
necessarily the same as the initial viewport coordinate system, is it?

The introduction seems to shy away from making an explicit statement
about this.
