United Linux was an attempt by a consortium of Linux distributors to create a common base distribution for enterprise use, so as to minimize duplication of engineering effort and form an effective competitor to Red Hat. The founding members of United Linux were SUSE, Turbolinux, Conectiva (now merged with MandrakeSoft to form Mandriva) and Caldera International (later renamed to The SCO Group). The consortium was announced on May 30, 2002. The end of the project was announced on January 22, 2004.
With the rise of Linux during the 1990s, Linux distributions proliferated. Since the Linux kernel and GNU were both free software, anyone could put together and market a distribution. Many industry observers feared fragmentation and wide-ranging incompatibility, similar to the UNIX wars of the early 1990s.
The first moves towards the United Linux project were made at COMDEX in November 1999. There were a number of false starts, but the participants consistently agreed that a unified Linux platform for business made sense. The key factors for success were identified early in 2000.
Starting in March and April 2002, the United Linux board put together a base technical specification, getting input from the four consortium members and their business partners and vendors.
UnitedLinux, LLC was formed May 29, 2002 [1] and the project was announced to the world on May 30, 2002. Two legal agreements were signed by the founding members at this time, the Master Transaction Agreement (MTA) and the Joint Development Contract (JDC); the JDC was also signed by UnitedLinux, LLC. These contracts provided, in part, that intellectual property related to UnitedLinux Software (with certain exceptions) would be assigned to UnitedLinux, LLC. Further, "[e]ach member shall have a broad, royalty-free license to all intellectual property rights in the UnitedLinux Software, entitling each member to "use, copy, modify, distribute, market, advertise, sell, offer for sale, sublicense ... in any manner the Software, including the rights to make derivative works of the Software, to provide access to the Source Code and/or Object Code to any third party, to incorporate the Software into other products or bundle the Software with other products for its own business purposes and any other unlimited right of exploitation"; existing open source licenses, such as the GNU General Public License, also continued to apply. Disputes were to be settled via International Chamber of Commerce (ICC) arbitration. [2] [3]
A first beta was released to United Linux member partners on August 14, 2002, a public beta was released on September 25, 2002 and United Linux 1.0 was released on November 19, 2002.
For a detailed case study in what led one of the four partners to embrace the ideals of United Linux see Caldera OpenLinux.
The distribution was based on SUSE Linux and the Linux Standard Base, with the plan being for SUSE to do most of the engineering work and SCO, Turbolinux and Conectiva primarily to market the distribution in their territories and markets. [4]
It was planned that version 1.0 would take six to eight months to release, be the current version for one year and be supported for another year after the release of 2.0. Minimum technical requirements were:

On January 20, 2004, SCO filed a lawsuit, against Novell, the then-current owner of SuSE. [5]
The end of United Linux was announced in a Novell press conference on January 22, 2004 by Richard Seibt, president of the SUSE division. The stated reason was that the SCO v. IBM lawsuit and The SCO Group's public attacks on Linux had made the alliance unworkable. [6]
It emerged that no real work had been done on United Linux since soon after SCO v. IBM had started, and that SUSE had ceased active participation around this time. The last United Linux announcements were of Oracle Corporation support for it on 13 March 2003, and of AMD64 CPU support on 22 April 2003.
While some have reported that UnitedLinux ended, in fact the group did not gain consensus to dissolve the partnership and the legal entity remains in effect.
The SCO v. Novell complaint was amended on February 3, 2006 to add copyright infringement claims, relating to Novell's distribution of SuSE Linux. [7] Novell responded on April 10 by filing a Request for Arbitration with the ICC, and asking that SCO's claims be stayed in the district court. They argued in the Request that through the MTA and JDC, "the UnitedLinux members agreed that each member would have an irrevocable, perpetual, and worldwide license to use and unlimitedly exploit any intellectual property rights of the other members in the UnitedLinux Software, which would be transferred to the LLC for this very purpose." [2] [8] Novell's motion to stay was granted in part, for those of SCO's claims relating to SuSE. [3]
On September 14, 2007, SCO filed for bankruptcy, [9] and on November 13, the court ruled at SCO's request that the arbitration was automatically stayed. [10]
SuSE filed a motion to lift this stay on November 10, 2009. [11] However, SCO objected on December 15, [12] and SUSE's motion was denied on January 15, 2010. [13]
YaST is a Linux operating system setup and configuration tool.
Novell, Inc. was an American software and services company headquartered in Provo, Utah, that existed from 1980 until 2014. Its most significant product was the multi-platform network operating system known as Novell NetWare.
SCO Group, Inc. v. International Business Machines Corp., commonly abbreviated as SCO v. IBM, is a civil lawsuit in the United States District Court of Utah. The SCO Group asserted that there are legal uncertainties regarding the use of the Linux operating system due to alleged violations of IBM's Unix licenses in the development of Linux code at IBM. The lawsuit was filed in 2003, it has lingered on through the bankruptcy of SCO Group and the adverse result in SCO v. Novell, and was reopened for continued litigation by order of a new judge on June 14, 2013. Pursuant to the court order reopening the case, an IBM Motion for Summary Judgment was filed based upon the results of the Novell decision. On December 15, 2014, the judge granted most of IBM's motion, thereby narrowing the scope of the case, which remained open. On March 1, 2016, following a ruling against the last remaining claims, the judge dismissed SCO's suit against IBM with prejudice. SCO filed an appeal later that month. In February 2018, as a result of the appeal and the case being partially remanded to the circuit court, the parties restated their remaining claims and provided a plan to move toward final judgement.
The SCO Group was an American software company in existence from 2002 to 2012 that became known for owning Unix operating system assets that had belonged to the Santa Cruz Operation, including the UnixWare and OpenServer technologies, and then, under CEO Darl McBride, pursuing a series of high-profile legal battles known as the SCO-Linux controversies.
Caldera International, Inc., earlier Caldera Systems, was an American software company that existed from 1998 to 2002 and developed and sold Linux- and Unix-based operating system products.
Groklaw is a website that covered legal news of interest to the free and open source software community. Started as a law blog on May 16, 2003, by paralegal Pamela Jones ("PJ"), it covered issues such as the SCO-Linux lawsuits, the EU antitrust case against Microsoft, and the standardization of Office Open XML.
Within the free software and the open-source software communities there is controversy over whether to refer to computer operating systems that use a combination of GNU software and the Linux kernel as "GNU/Linux" or "Linux" systems.
UnixWare is a Unix operating system. It was originally released by Univel, a jointly owned venture of AT&T's Unix System Laboratories (USL) and Novell. It was then taken over by Novell. Via Santa Cruz Operation (SCO), it went on to Caldera Systems, Caldera International, and The SCO Group before it was sold to UnXis. UnixWare is typically deployed as a server rather than a desktop. Binary distributions of UnixWare are available for x86 architecture computers. UnixWare is primarily marketed as a server operating system.
In a series of legal disputes between SCO Group and Linux vendors and users, SCO alleged that its license agreements with IBM meant that source code IBM wrote and donated to be incorporated into Linux was added in violation of SCO's contractual rights. Members of the Linux community disagreed with SCO's claims; IBM, Novell, and Red Hat filed claims against SCO.
SCO v. Novell was a United States lawsuit in which the software company The SCO Group (SCO), claimed ownership of the source code for the Unix operating system. SCO sought to have the court declare that SCO owned the rights to the Unix code, including the copyrights, and that Novell had committed slander of title by asserting a rival claim to ownership of the Unix copyrights. Separately, SCO was attempting to collect license fees from Linux end-users for Unix code through their SCOsource division, and Novell's rival ownership claim was a direct challenge to this initiative. Novell had been increasing their investments in and support of Linux at this time, and was opposed to SCO's attempts to collect license fees from Novell's potential customers.
Beginning in 2003, The SCO Group was involved in a dispute with various Linux vendors and users. SCO initiated a series of lawsuits, the most known of which were SCO v. IBM and SCO v. Novell, that had implications upon the futures of both Linux and Unix. SCO claimed that Linux violated some of SCO's intellectual properties. Many industry observers were skeptical of SCO's claims, and they were strongly contested by SCO's opponents in the lawsuits, some of which launched counter-claims. By 2011, the lawsuits fully related to Linux had been lost by SCO or rendered moot and SCO had gone into bankruptcy. However the SCO v. IBM suit continued for another decade, as it included contractual disputes related to both companies' involvement in Project Monterey in addition Linux-related claims. Finally in 2021 a settlement was reached in which IBM paid the bankruptcy trustee representing what remained of SCO the sum of $14.25 million.
openSUSE is a free and open-source Linux distribution developed by the openSUSE project. It is offered in two main variations: Tumbleweed, an upstream rolling release distribution, and Leap, a stable release distribution which is sourced from SUSE Linux Enterprise.
SUSE Linux Enterprise (SLE) is a Linux-based operating system developed by SUSE. It is available in two editions, suffixed with Server (SLES) for servers and mainframes, and Desktop (SLED) for workstations and desktop computers.
SUSE is a Luxembourgish multinational open-source software company that develops and sells Linux products to business customers. Founded in 1992, it was the first company to market Linux for enterprise. It is the developer of SUSE Linux Enterprise and the primary sponsor of the community-supported openSUSE Linux distribution project. While the openSUSE "Tumbleweed" variation is an upstream distribution for both the "Leap" variation and SUSE Linux Enterprise distribution, its branded "Leap" variation is part of a direct upgrade path to the enterprise version, which effectively makes openSUSE Leap a non-commercial version of its enterprise product.
Caldera OpenLinux (COL) is a defunct Linux distribution. Caldera originally introduced it in 1997 based on the German LST Power Linux distribution, and then taken over and further developed by Caldera Systems since 1998. A successor to the Caldera Network Desktop put together by Caldera since 1995, OpenLinux was an early "business-oriented distribution" and foreshadowed the direction of developments that came to most other distributions and the Linux community generally.
SUSE Linux is a computer operating system developed by SUSE. It is built on top of the free and open-source Linux kernel and is distributed with system and application software from other open source projects. SUSE Linux is of German origin, its name being an acronym of "Software und System-Entwicklung", and it was mainly developed in Europe. The first version appeared in early 1994, making SUSE one of the oldest existing commercial distributions. It is known for its YaST configuration tool.
Linux began in 1991 as a personal project by Finnish student Linus Torvalds to create a new free operating system kernel. The resulting Linux kernel has been marked by constant growth throughout its history. Since the initial release of its source code in 1991, it has grown from a small number of C files under a license prohibiting commercial distribution to the 4.15 version in 2018 with more than 23.3 million lines of source code, not counting comments, under the GNU General Public License v2 with a syscall exception meaning anything that uses the kernel via system calls are not subject to the GNU GPL.
ZYpp is a package manager engine that powers Linux applications like YaST, Zypper and the implementation of PackageKit for openSUSE and SUSE Linux Enterprise. Unlike some more basic package managers, it provides a satisfiability solver to compute package dependencies. It is a free and open-source software project sponsored by SUSE and licensed under the terms of the GNU General Public License v2 or later. ZYpp is implemented mostly in the programming language C++.
Caldera was a US-based software company founded in 1994 to develop Linux- and DOS-based operating system products.
Open source license litigation involves lawsuits surrounding open-source licensed software. Many of the legal rights of open source software licensors enforceable against users violating licensing agreements are untested by the U.S. legal system. Free and open source software (FOSS) is distributed under a variety of free-software licenses, which are unique among other software licenses. Legal action against open source licenses involves questions about their validity and enforceability.
