* Caldera also incorporated LISA (Linux Installation and System Administration),<ref name="Hughes_1996_CND"/> which had been developed by the German [[Linux Support Team]] (LST) for their own Linux distribution.<ref name="LST_1997"/>

More than just a [[Software componentry|component]] for Novell, Caldera had assembled the components needed to create a [[Value-added reseller|VAR]] platform. However, Caldera faced a [[bootstrapping]] problem. OEM VAR applications often depended crucially on other companies' [[business software|commercial]] [[Application software|applications]]. Since these other applications hadn't been ported to [[Linux]] yet, they couldn't meaningfully port their own applications. Caldera responded by creating a [[Object file|binary applications package]], which allowed Linux to run [[UnixWare]] and [[OpenServer]] applications, the Linux [[Application Binary Interface]] (ABI) project,{{cn|date=November 2019}} and by assisting [[Santa Cruz Operation]] (SCO) in creating the [[Linux Kernel Personality|Linux Kernel Personalities]].<ref name="SCO_UW7"/>{{disputed inline|for=LKP did not arrive until years later|date=November 2019}} Linux Kernel Personalities was worked on to bring Linux application compatibility to [[SCO Unix]] (formerly UnixWare) and OpenServer. "''The idea was to enable [[Software developer|developers]] to write for both, Unix and Linux, with a common Application Programming Interface (API) and common Application Binary Interface (ABI). That way, developers didn't have to work so hard, and Unix users, the client base we inherited from SCO, could run Linux applications.''"<ref name="Vaughan-Nichols_2003"/>{{disputed inline|for=Cited source is talking about post-SCO acquisition Caldera International, not Caldera Network Desktop era|date=November 2019}}

Caldera also supported [[Alan Cox]] in his work on [[Symmetric multiprocessing|SMP]].{{when|date=May 2014}}<ref name="Cox_BKL"/> If Linux displaced Unix on the Intel x86 platform, then [[Sun Microsystems]] wouldn't have a low-end Unix path. This point becomes more interesting in light of SCO's litigation eight years later [[SCO v. IBM|against IBM]] in 2003.{{Relevance inline|paragraph|date=November 2019}} That is, [[IBM]] was not the company involved in the SMP work, and moreover, the company most directly involved is the company that later became the [[SCO Group]], essentially SCO suing IBM for work it itself did.{{citation needed|date=May 2014|reason=When did they support Alan Cox? Caldera, Inc. was not the same company as Caldera Systems, Inc. (and its successors). Caldera Systems, Inc. was not the successor of Caldera, Inc., but a spin-out. Therefore it is important to sort out the dates and names.}}
