Good to know. And I´d rather not fiddle with fstab, if it can be avoided.
That´s what I wanted to achieve by using systemd, i.e manage the mount behaviour.
In my post #16 I outlined how I´d like to configure a file /etc/systemd/system/media-rosika-74C1-30C7.mount
Yet I´m not bold enough to go through with the plan without obtaining an expert opinion about it first.
