Aha ! That I missed!! This makes sense. I thought a device as a
docking station is hanlded seperate, with the tags for the seat set
like seat1 ot seat2.
Just attach to seat0.

Of course. I only reacted this way while I was only gave a situation
as example, and not a suggestion to create a different policy, and got
annoyed.

Yes.

I understand that with loginctl attach you can assign a device to
seat0, making it a docking device (other programs should pick this up
of course), this creates a permanent rule. I will experiment with it.
I've got three of these plugable devices.

Earlier I've given an example about handling the first device as a
docking station, and every next as extra seat. This is not a suggested
default, but a situation as example., and how the system can handle
this situation compared too what you want.

Thanks a lot  for clearing this,

Stef

Well maybe me.
