Look this is getting us nowhere.

You do not seem to understand my point.

How does this rule look like? I'm asking because I cannot immagine one.

Earlier in this thread I've described the scenario of the first
plugable device being a docking station, and every next plugable
device an extra seat.

This logic can't be done with "simple" rules like in udev. Plugable
devices do not have unique id like partitions on block devices have,
so the rules can only be very generic. Every plugable device is a seat
or a docking station. There can't be something like I've described
above, the first a docking station, and every next an extra seat.
Isn't it?

In my opinion the setting of the tags "seat" in udev is not the best
place. They should be grouped in udev, and the group of devices is
made an extra seat or docking station by GDM or any other service like
logind, that I do not know.

A gui/message on the screen of the admin that a group of devices is
detected and asking to the user what to do is in my opinion also very
nice.
