After installing of new fedora 18 version at work, I was looking unsuccessfully for rc.local. TO modify some typical work routines.
From Fedora documentation
3.2.4. rc.local no longer packaged
The /etc/rc.d/rc.local local customization script is no longer included by default. Administrators who need this functionality merely have to create this file, make it executable, and it will run on boot.
touch /etc/rc.d/rc.local chmod +x /etc/rc.d/rc.local
