Nothing in FHS says an OS can't use directories not in the FHS.

What you neglected to show was where NTPsec installed itself?

By default, my NTPsec installed here:

-rw-r--r--  1 root  wheel  71992 Sep 27 16:01 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ntp/packet.py

Which is a little odd, but no way in conflict with the FHS.

Check out your root directory.  It still has /bin, /dev, /etc, /opt,
/sbin, /usr, /var, and most of the other things you would expect.  And
they are used in the way the FHS would approve of.

So, I still fail to see an issue here.

You really think I did not test it before my last reply?  I got NTPsec
pieces spread all over now on macOS since the last few changes.

I fail to see the problem there?  Or what you are trying to show?
Or why I should care?

Why would you even do that?  You totally lost me.

Sigh, I hate to sound like a broken record, but we have all agreed
several times today that we would like to do without PYTHONPATH.  No
need to say it is a point of difference, it is not.

How about we work on that instead?
