Uptake of native Linux ZFS port hampered by license conflict
Found on ArsTechnica on Tuesday, 08 June 2010
Although the code is functional and available for download (but not production-ready yet), it cannot be merged upstream or shipped in binary form with the Linux kernel due to a licensing conflict.
In a message on the ZFS-Fuse mailing list, Behlendorf says that his team has unsuccessfully been urging Oracle to change the ZFS license in order to resolve the compatibility problem.
Sun (and now Oracle) has declined to do so for Solaris, creating artificial barriers for adoption of the code in Linux. A native Linux ZFS port has considerable technical value, but it won't see much adoption as long as the licensing conflict exists.
Oracle should quit being so stuck up and re-release the code under the GPL after all the discussions they have caused in the GPL world by buying MySQL and Sun.
