Linux was a phenomenon waiting to happen. The computer industry suffered from a rift. In the 1980s and 1990s, people had to choose between inexpensive, market-driven PC operating systems from Microsoft and expensive, technology-driven operating systems such as UNIX. Free software was being created all over the world, but lacked a common platform to rally around. Linux has become that common platform.

For several years , Red Hat Linux was the most popular commercial distribution of Linux. In 2003, Red Hat, Inc. changed the name of its distribution from Red Hat Linux to Fedora Core and moved its commercial efforts toward its Red Hat Enterprise Linux products. It then set up Fedora to be:

• Sponsored by Red Hat

• Supported by the Linux community

• Inclusive of high-quality , cutting-edge open source technology

• A proving ground for software slated for commercial Red Hat deployment and support

Red Hat Enterprise Linux, on the other hand, became the basis for Red Hat's fully supported product line, geared toward big companies with the need to set up and manage many Linux systems. After taking its software through about a year and a half of Fedora releases (about once every six to nine months), a commercial Red Hat Enterprise Linux (RHEL) product line is released that includes:

• Subscription service to RHEL that offers stable, tested software (mostly the same software in Fedora Core that has gone through rigorous testing)

• Multiple support programs, ranging from an online knowledge base to assistance with custom deployment, engineering, and software development

• Official documentation, training, and certification programs

Fedora Core has, itself, become a respected and active Linux distribution that thousands of people use worldwide as a desktop, server, or programming workstation. It is the best way to get the latest Linux software that is being built on a foundation for enterprise-quality systems.

Using Fedora Core is a great way to get a head start learning the features of upcoming RHEL releases. The complete Fedora Linux operating system (referred to as Fedora Core 6) is included on the DVD that comes with this book. The two CDs you get include a Fedora Core Live CD (which doubles as a network install CD) and a Fedora Extras CD (containing hundreds of extra software packages).
