I don't believe many folks think about the OS in the
strictly narrow view that it is "only a kernel existing
below higher abstractions", as much as they accept the OS as
encompassing the OS kernel and all the ooey and gooey
interfacing layers on top. I suppose you might call that a
"system", but such a word is far too ambiguous. IOWs: it may
not be technically correct, but it is the accepted norm.
