CAOS Linux was an RPM-based Linux distribution. It aspired to be community maintained and managed. Infiscale described its GravityOS as "[including] the small footprint of Caos"  indicating a certain level of influence from the discontinued distribution. The name is known to have been capitalized in various ways: cAos and CAos were used with earlier releases; CAOS and Caos were used on the web site's main pages.
CAOS Linux combined aspects of Debian, Red Hat Linux/Fedora, and FreeBSD in a manner that aspired to be stable enough for servers and clusters, for a life cycle of 3 to 5 years. The CAOS Project was part of a larger organization (The CAOS Foundation) which was a team of open source developers working and using resources together.
As of February 2015, the official website is not live any more, the domain name having been re-attributed. DistroWatch has been listing CAOS Linux as discontinued since at least November 2014.
