Lunar 1.6.4 for Intel 686 architecture. Lunar is a source based Linux distribution with a unique package management system which builds each software package, or module, for the machine it is being installed on. Though it can take a while to do a complete Lunar installation it's worth it as it tends to be quite fast, once installed! In the beginning Lunar was a fork of Sorcerer GNU Linux (SGL). The fork occurred in late January to early February of 2002 and was originally made up of a small group of people who wanted to collaboratively develop and extend the Sorcerer technology. The original name for the project was Lunar-Penguin but the group decided to re-christen it Lunar Linux while the Lunar-Penguin name has become a sort of umbrella which the team could use if they decide to collaboratively develop something besides Lunar Linux.
