Fedora: Booting Fedora LIVE to RAM
Fedora live images do not include the "Boot to RAM" option any more. This is not a big problem as the scripts needed to boot to RAM are still there.
You just need to add rd.live.ram as boot option.
To do that, highlight "Start Fedora Live" using the keyboard keys and press TAB to edit boot command line. Add rd.live.ram and press Enter.
