The first time a user logs into the default desktop for the rhel7 beta, they're prompted to set a language, add online accounts, and dropped into a help menu right from the start. While this might be nice for brand new users, it's certainly not ideal for everyone.
Turns out there's a very simple way to prevent this annoyance from spreading further than it needs to.
echo "yes" >> ~/.config/gnome-initial-setup-done
Alternatively, if you want to do this for every new user on your system rather than dealing with it one at a time, simply drop the .config directory and file into /etc/skel before you create your new users.
