Red Hat Linux
Description
Red Hat Linux, assembled by the company Red Hat, was a popular, "middle-aged" Linux distribution (not as old as Slackware but older than Ubuntu) upon its discontinuation in 2004.
Red Hat Linux 1.0 was released on November 3, 1994. It is the first Linux distribution to use RPM as its packaging format, and over time has served as the starting point for several other distributions, such as Mandriva Linux and Yellow Dog Linux.
Since 2003, Red Hat has discontinued the Red Hat Linux line in favor of Red Hat Enterprise Linux (RHEL) for enterprise environments. The source code of RHEL remains available for free, and has been the basis for several other Red Hat Enterprise Linux clones such as CentOS. Fedora, developed by the community-supported Fedora Project and sponsored by Red Hat, is the free version best suited for the home environment. Red Hat Linux 9, the final release, hit its official end-of-life on April 30, 2004, although updates were published for it through 2006 by the Fedora Legacy project until that shut down in early 2007.
