Users had originally been promised that the Janus Linux support system, which allows unmodified Linux software to be run on the Solaris platform, would be available soon after the Solaris 10 launch earlier this year.
Sun is now planning to release Janus next year. The Zettabyte File System, designed to improve the management of data storage on the Solaris platform, will also not be ready until next year. It too had been promised for this year.
Solaris is under pressure from Linux and other Unix variants and the delay in releasing these features will be a blow to Sun in convincing enterprise users that Solaris can provide a one-stop-shop in the datacentre.
Solaris is expected to become fully open source by this summer.
