"Apart from the new Gnome 3 desktop, another noticeable feature on the
platform is the systemd configuration. Systemd replaces SysVinit and
Upstart for system and session management and brings a faster boot
experience. The Fedora Project has added a cloud based BoxGrinder
appliance builder tool to the platform to aid developers. Fedora 15
also comes with Linux 2.6.38, the SystemD configuration utility and a
new firewall system. Fedora 15 will also come with a range of new
applications including LibreOffice and Mozilla Firefox 4 so that it has
greater out-of-the-box functionality."
