Hello Bob, I'll reply via the NUT mailing list since others may be 
interested, and the list will archive the discussion.

Putting the shutdown script in /usr/lib/system/system-shutdown so that 
systemd will execute it as late as possible makes it difficult to debug 
what happens, or doesn't happen, since when the script is executed, it is 
no longer possible to write out any trace statements.

So I suggest that temporarily you use the systemd service unit approach 
which will place a record in /var/log/messages. This is easier to debug. 
Once you have found out why the required shutdown has not happened, you 
can test the fix, and when it works go back to using a script in 

Don't forget that you will have to initialize the service unit with a 
command such as
   systemctl --system reenable /etc/systemd/system/ups-delayed-shutdown.service
