This sounds like a bug.
I think gdm misses a configuration option to enforce that it always
takes posession of a certain tty device. Without that we might sometimes
have a race here where the systemd status printing stuff might open
/dev/tty1 for a short moment to print a message (i.e. the green [ OK ]
messages), and X11 at the very same time is started and ends up thinking
that /dev/tty1 is already taken.

Yes, I fully agree with this.
