Back in the day Fedora Core 5 was the most recent release, Fedora Unity created so-called live media using Kadischi, then actively developed by Jasper Hartline, another valued Fedora Unity member. In those days, live media could only have a read-only root file system and was not as feature-rich as live media is today. However, just before Revisor came to life, two applications were developed; pungi for creating installation media, and livecd-tools for creating live media. These two applications did their work well; The media composed for a genuine Fedora release, including many different custom live media spins were, and still are, created with these tools, not to mention the many downstream consumers that use these tools to do the exact same thing. Immediately, the Revisor developers set themselves a target to provide a single interface to both of those tools, and give the user more flexibility so that the user could bend the rules without breaking them.
