I think they're defining "operating system" as "an implementation of
the Portable Operating System Interface" (POSIX), which is a
standardized definition of an "operating system" agreed upon by the
many contributors.
POSIX grew out of an attempt to combine BSD and SYSV flavors of UNIX and
have a "standard" to write against. In simple terms, if you wrote code
that conformed to POSIX standard, you should be able to compile & run it
on systems that also conformed to POSIX standard. POSIX is *not* a
"definition of an operating system", it is a "definition of the
*interface to* an operating system". Major difference...
