A way to avoid the smartmontools systemd service to fail is to switch the Service type from notify to forking. This after adding the "-q nodev0" flag to the /etc/default/smartmontools smart_options variable.
systemctl edit smartmontools [Service] Type=forking then systemctl daemon-reload and restart samrtmontools/ Why is smartd of type notify? Does it send notification to systemd via sd_notify?
