Hello,
I finally got around to playing with these....
Here is what I found.

This is a typo... It should be Type=oneshot

Can this be moved from /usr/lib/systemd/scripts to /usr/lib/systemd/system
since the scripts directory does not exit and I don't think we
want to be creating directories under /usr/lib/systemd/
Finally, Its a bit confusing on how to get the new /run/sysconfig/nfs-utils
created. systemctl start nfs-config does not do it but
systemctl restart nfs-config.
Doesn't this also mean every time /etc/sysconfig/nfs is edited
a systemctl restart nfs-config has to be done to update the
new /run/sysconfig/nfs-utils and then restart the server
they are reconfigured? Or am I missing something?
If I'm not it seems a bit overly complicated and its not
appeared to be documented anywhere...
