A few versions back, Fedora stopped using the initab file. Here is the new method to set Fedora 17 to boot to a CLI rather than a GUI.

1) Remove the default.target, run the following command

# rm -f /etc/systemd/system/default.target

2) Set the system to boot into CLI, run the following command

#  ln -s /lib/systemd/system/multi-user.target /etc/systemd/system/default.target

3) Reboot
