Seems KDE's new login/session manager which is supposed to replace sddm dropped FreeBSD support and will be systemd only.
I could rant about this being a typical techbro linux move (and about fedora, as far I can see in this case) or ask on the kde discuss what's the real deal, but I am tired of this, so tired...
It is sending exactly the wrong message to other OS ports and it's why I left the GNU/Linux world. Move fast, break things...
*sigh* Ok, I should start worrying about plasma6's general direction now and slowly looking for another DE here on FreeBSD. It's not worth the struggle.
