The history of RPM is inextricably linked to the history of Linux, so a bit of Linux history may be in order. All for the cost of the time required to download, install, and configure the software. The amount of tinkering required with these distributions has varied widely. Produced by a company of the same name, this Linux distribution was different. One of the key decisions a new Linux user needs to make is which of the many different parts of the distribution to install on their system.
Most distributions use some sort of menu, making it easy to pick and choose.
Red Hat Linux is no different. But what is different about Red Hat Linux is that the creators of the distribution wanted their customers to have the the ability to make the same choices long after the installation process was over. Over time, Red Hat Linux has become the most popular distribution available today. But until now, there has been precious little in terms of RPM documentation. You could say that RPM's ease of use has made detailed instructions practically unnecessary, and you'd be right.
