David - One additional note. In the situation discussed on the opensuse forum, I had manually entered the share mount in fstab - not in NFS Client. I did so by literally copying the fstab entry for one of the pre-existing share mounts; see the code in the first post at https://forums.opensuse.org/showthread.php/556018-unknown-option-x-systemd-automount?p=3043273#post3043273.
