Init-Scripts

You will need to do some init script modifications. The first init script that will be called on fedora systems is /etc/rc.d/rc.sysinit, which is where you have to comment out the remount for / to read-write mode, and insert the mounts for the ramdisks. You might want to disable some daemons, that you don't need, and make some changes in /etc/fstab, according to your configuration.
