SCO, Conectiva, SuSE Linux and Turbolinux released a beta version of the UnitedLinux operating system in September and have claimed that more than 15,000 copies have been downloaded.
Each of the four vendors to release a separate server software product based on the core operating system, adding their own set of unique features on top of the common base.
The SCO Group, formerly Caldera International, is expected to release SCO Linux Server 4.0, a server version of its operating system powered by UnitedLinux 1.0.
UnitedLinux Version 1.0 will be compliant with the Linux Standards Base (LSB), a set of technical requirements managed by the Free Software Group, the group has said.
SuSE, whose server operating system was chosen as the foundation of UnitedLinux, is also expected to provide more details of plans for a corporate desktop Linux operating system.
It has previously announced plans to release a desktop operating system that can run Microsoft Windows applications.
