I just want a working systemd/wayland desktop system. So basically, a 
full-weight normal desktop.

I've got this one selected, /desktop/plasma/systemd

Not after a minimalist system, and if it pulls in X that's fine. 
(Actually, I've installed X, and at the moment it blows up on me, but if 
I can get Wayland working, I don't see the point in debugging it until I 
need to ...)

I'll need something like sddm, because I'll have multiple users logged 
in simultaneously. I was trying to use qtgreet as per the "Wayland 
Landscape" page, but the package doesn't seem to exist ... I'd rather 
avoid gnome/gdm and gtkgreet, lightdm and sddm look like X11 (and I said 
I didn't want to debug it :-), and tuigreet looks like it might not 
support multi-user/multi-head.

Still, if I can get plasma running, I can work from there ...
