The POSIX standard is a set of features that Unix-like operating
systems should provide, and not a standard for the design of any
operating system in general.

POSIX = "Portable Operating System Interface for Unix".  Note the "for
Unix" part of the acronym.  That hardly establishes it as "a standard
for what an OS should provide", in the general sense of your
statement.

Though I haven't confirmed it, according to some sources many of the
open-source Unix-like operating systems aren't fully POSIX compliant.
GNU/Linux, FreeBSD, OpenBSD, and NetBSD are on the not-fully-compliant
list.

You should do the research yourself to answer the question "which OS
comes closer".  You'll have to provide a comparison of the compliant
and non-compliant features of OpenVMS (with the POSIX libaries
installed) versus any particular distribution of Linux or whichever
Unix variant you have in mind.  I'm sure it will be informative for
all of us to see the results of your research.
