boot without login

I have loaded raspberrypi-fedora-remix-14-r1.img (against the advice!) and it runs very well. I had to give it my password 4(?) times and had to fix the clock later but it seems OK - but no sound yet (as I think I have to accept at present ?)

I need Firefox to show a streaming webcam picture - With Debian I tried Chromium but that crashed after a few hours. Fedora has run 30 hours now and all is well.

BUT

I need a system that comes up on its own after a power outage and does not demand a password.
Google tells me to modify /etc/gdm/custom.conf for Fedora auto-boot - but that file is not present.

Does anyone know how to do auto-boot?

I haven't an answer, but I also need the same thing for a car computer project that needs to boot to the GUI when the ignition is started without any login or other user intervention. I've never had a problem doing this with a PC-based Linux and it seems odd that it isn't set up for this.
