SCO last month sent its partners a letter designed to update them on the actions it was going to take with respect to LKP to address those IP issues. "It is important to assure all users of UnixWare with LKP that they will be held harmless with respect to the SCO IP issue and may continue using the materials they have already received as we have announced for customers who have licensed any of SCOs Linux based products," John Maciaszek, SCOs UnixWare Product Manager, said in the letter.Maciaszek also contended in the letter that the LKP "does not need or use any of the Linux kernel to support the execution of Linux applications, consequently we do not expect this rework to have any impact on the utility of LKP for our customers." But members of the open-source community disagree and say SCOs legal claims that Linux is an unauthorized derivative of Unix and contains its proprietary intellectual property could be significantly weakened if it is shown that SCO incorporated parts of the Linux kernel into its Unix source code without giving these back to the community and since no copyright notices have been displayed attributable to Linux. It is also no secret that Caldera International, which acquired the Santa Cruz Operation (SCO)a UnixWare business and professional-services organizationin August 2000, wants to unify Linux and Unix on one platform. In an eWEEK report based on comments made by Calderas then CEO Ransom Love in February 2001, Love said Caldera would make UnixWare binary-compatible with Linux, allowing UnixWare customers to run Linux applications. On the flip side, Caldera Linux would gain UnixWares best enterprise and database management features. These included large file system support, asynchronous input/output (I/O), the UnixWare API, extended developer kit and multipath I/0, he said at that time. Freelance reporter Jason Perlow contributed to this article.
SCO has also examined the Linux RPM CD that shipped with the UnixWare Media Kits to expunge any material that was thought to have any IP issues, he said.
