Caldera OpenLinux is a defunctLinux distribution produced byCaldera, Inc. (and its successorsCaldera Systems andCaldera International) that existed from 1997 to 2002. Based on the German LST Power Linux distribution, OpenLinux was an early high-end "business-oriented" distribution that included features it developed, such as an easy-to-use, graphical installer and graphical and web-based system administration tools, as well as features from bundledproprietary software. In its era, Caldera OpenLinux was one of the four major commercial Linux distributions, the others beingRed Hat Linux,Turbolinux, andSuSE Linux.[nb 1]
By 1994, under CEORay Noorda's purview,Novell Corsair was a project run by Novell's advanced technology group that sought to put together adesktop metaphor withInternet connectivity and toward that end conducted research on how to better and more easily integrate and manage network access for users. At the time, the Internet was dominated byUnix-based operating systems, but the Novell group saw the Unixes of the day as being too hardware intensive, too large, and charging too much in license fees. They became convinced thatLinux offered the best possible answer for the operating system component, and started building code towards that purpose, including contributing work onIPX networking forNetWare andWine compatibility layer for Windows. However, Noorda departed from Novell and under new management, the Linux role in Corsair was dropped.[3]
Caldera, Inc. was founded in 1994 byBryan Wayne Sparks and Ransom H. Love and received start-up funding from Noorda's Utah-focusedCanopy Group, and Caldera became one of the first commercial companies putting out aLinux distribution.[4] That first distribution wasCaldera Network Desktop, which was based onRed Hat Commercial Linux.[5][6] It seemed primarily aimed at the office desktop and custom solutions markets.[6]
One of the features of Caldera Network Desktop was an installation component called LISA (Linux Installation and System Administration),[6] which had been developed with the Germany-basedLinux Support Team (LST).[7] In terms of Linux distributions, that group was responsible for LST Power Linux, aSlackware-derived distribution that had been maintained by LST since its first incarnation in 1993.[8] Caldera Network Desktop ended sales in March 1997.[9]
Caldera, Inc. collaborated with the LST staff, which by then had becomeLST Software GmbH, and its LST Power Linux distribution, which was made the basis of their following product.[8] Then in May 2007, it was announced atLinux Kongress that Caldera, Inc. was acquiring LST and its development center inErlangen, Germany,[7] thus creatingCaldera Deutschland GmbH.[8]
This new product was named Caldera OpenLinux.[9] (The name OpenLinux tended to annoy people associated with other Linux distributions, falsely suggesting as it did that the other distributions were not open.[1]) Review copies of it became available by March 1997.[10] By one account, it was the first commercial distribution to include version 2 of theLinux kernel.[11]
Caldera offered three versions of OpenLinux, with one for hackers and the other two for resellers and commercial users.[1] Alternatively, the three versions could be seen as a base version, a workstation version, and a server version.[10] Pricing could also change; at one point, the product breakdown was:
Earliest versions of OpenLinux came onCD-ROMs for installation, but it was often necessary to createfloppy disks for the initial boot, depending upon theBIOS capabilities of theIBM PC compatible system being installed.[9] That floppy was not shipped by the distribution and had to be cut by the user.[10]At another point in time, Caldera OpenLinux was also available on a retail basis, in the form of a CD-ROM for installing Linux on a PC that sold for US$49.[12]
OpenLinux typically came with a separate CD-ROM called the Solutions CD, which is what delivered the commercial software. These included such powerful enterprise products as theAdabas D database management system fromSoftware AG.[1] Use of these components required activation of a license key.[10] A review inComputerwoche assessed the initial Caldera OpenLinux release as providing an easy-to-use distribution at an attractive price-to-performance point for those exploring Linux.[10]
In September 1998, Caldera, Inc. spun offCaldera Systems, which handled OpenLinux going forward, including development, training, services, and support.[13]
The Caldera Systems distribution used theKDE desktop.[14] Other open-source components that it came with includedQt andWine.[15] There was also a non-commercial version ofStar Office.[16] Support forISDN was bundled into the product, which was a benefit in the German market.[10]
But Caldera Systems focused on a high-end Linux product and its Linux distribution became rich with features with bundledproprietary software. For instance, the company offeredNetWare for Linux, which included a full-blownNetWare implementation from Novell.[17]They licensedSun Microsystems'sWabi to allow people to run Windows applications under Linux.[18] Additionally, they shipped with Linux versions ofWordPerfect fromCorel as well as productivity applications fromApplixware.[15] Since many of their customers used adual boot setup, Caldera shipped withPowerQuest'sPartitionMagic to allow their customers to non-destructivelyrepartition theirhard disks.[15][19]
This approach led to a debate about the purity of Linux-based products. Caldera stated that: "We have produced a product that combines the best of open-source and commercial packages; we are doing Linux for business. We do add to it commercial packages that allow business users to easily integrate it."[20]
OpenLinux 2.2, released in April 1999, was seen as significantly improved from the previous year's1.3 release, especially in terms of it having a fully graphical and easy-to-use installation feature.[19] Ease of installation was an important criteria in selecting a Linux distribution,[21] and Caldera Deutschland had created this first fully graphical installer for Linux, called Lizard, starting in November 1998.[22] Several years later it was still receiving praise from reviewers.[23] The installer could even be started from aMicrosoft Windows partition.[19]
The improvements provided by the Lizard installer led to the technology publicationLinux Journal giving Caldera OpenLinux 2.3 its top award, Product of the Year.[24]
During 2000, Caldera Systems began the process of acquiring the Unix businesses of theSanta Cruz Operation. In March 2001 announced that it would be changing its name to Caldera International.[25]
Caldera OpenLinux 3.1 came out in June 2001.[26] Among the new softwares incorporated were Caldera's own Volution Manager and Volution Messaging Server, which were layers of functionality on top of Linux aimed at adding value to the operating system product.[2] The workstation edition of Caldera OpenLinux came with a requirement forper-seat licensing.[26] An extensive review of Caldera OpenLinux 3.1 inPC Magazine gave it 3 out of 5 'discs', behind the Red Hat and SuSE products which each got 4 out of 5.[2]
The last release of the product was Caldera OpenLinux 3.1.1 in January 2002.[27] OpenLinux 3.1 and 3.1.1 were used as the user-space basis for SCO's Linux Kernel Personality (LKP) product onSCO UnixWare.[28]

Caldera OpenLinux offered specific packages for e-commerce and secure-server configurations.[2] It was also aimed at the business connectivity domain.[1] AsPC Magazine wrote at the time, "Unusual for the Linux world, Caldera makes a strong cost-of-ownership argument in the corporate environment." It also said: "Unparalleled support and a wide range of products, including e-commerce solutions, make Caldera OpenLinux Server 3.1 a very attractive choice. Caldera's clear distinction between client and server distributions underlines the company's endeavor to appeal to the business community."[2]
In its era, Caldera OpenLinux was one of the four major commercial Linux distributions, the others beingRed Hat Linux,Turbolinux, andSuSE Linux.[1] In particular, these were the four that got the backing of hardware vendors such asHP andIBM, although Red Hat was clearly the primary recipient of such hardware support announcements.[1] And overall Red Hat had the broadest base of acceptance within the computer industry, with SuSE strong in Europe.[2]
By 2002, in the wake of thedot com bust, the Linux side of Caldera International was losing money badly; it was spending four times as much as it received in revenue.[29] The only Linux distribution company that was doing even somewhat well at the time was Red Hat.[30] Caldera International was further disadvantaged in that the Unix side of its business contributed most of its revenue and represented the products its resellers had the largest incentive to sell.[31]
United Linux was an attempt by a consortium of Linux companies to create a common base distribution for enterprise use and minimize duplication of engineering effort[32] and thereby form an effective competitor to Red Hat. The founding members of United Linux wereSuSE,Turbolinux,Conectiva, andCaldera International.[32] The consortium was announced in May 2002.[33] However, the UnitedLinux distribution would be based mostlySuSE Enterprise Linux rather than Caldera OpenLinux.[34] As such, the Caldera product name was changed to "Caldera OpenLinux powered by United Linux".[35] This effectively meant the end of the LST-/Caldera-based OpenLinux technology itself,[8] and the Caldera Deutschland GmbH office in Erlangen was shut down.[36]
In the event, United Linux did not last much longer. In June 2002, Caldera International had a change in management, withDarl McBride taking over as CEO from Ransom Love.[32] Caldera International soon changed its name toThe SCO Group.[37] The product name Caldera OpenLinux became "SCO Linux powered by UnitedLinux".[38] In May 2003, the SCO Group began issuing proclamations and lawsuits based upon its belief that its Unix intellectual property had been incorporated into Linux in an unlawful and uncompensated manner – thus commencing theSCO–Linux disputes – and stopped selling its own Linux product.[39] The United Linux effort itself collapsed as a consequence.[40]
In any case, Caldera OpenLinux had played a significant role in Linux history by establishing what would be necessary to create a mainstream, business-oriented system, with stability and support, out of the Linux kernel.[16]
