In a dramatic move toward reducing the boot time for Linux systems, two contenders for system start-up have emerged in recent years. One goes by the name “Upstart” (get it? — “start up” with the syllables reversed). The other is called systemd (for system daemon). If you hadn’t spotted a dramatic change in your Linux systems, you’re probably using one of the more conservative Linux systems. The difference between RedHat and Fedora today might really surprise you.
