It's has been that way since Fedora adopted systemd, which was in F15 or so IIRC? That makes 3.5y or so... On Fedora tty1 is the graphical login, since a long time. > What is this permissions business?

Dunno, it's about making sure logind knows about your session and on which VT it is, so that switching to/from it works correctly, and so that we can managed access to your audio cards and similar properly. And since very recently even access to input and gfx devices is managed by logind, so this becomes even more important. > > it cannot open a new VT. > > Why? Because you'd have to register that new VT with logind, and there's no way currently to do that, since creating a session is a one-way street, and you cannot create another session from an existing one, without involving some background process that is not part of any session.
