netinstall Image
The netinstall image boots directly into the installation environment, and uses the online Fedora package repositories as the installation source. With a netinstall image, you can select a wide variety of packages to create a customized installation of Fedora.
The Fedora Server netinstall image is a universal one, and can be used to install any Fedora Edition or your own set of favorite packages.
But there is no mention of the Everything image.
