It's not a GPL violation. OpenZFS works under Linux through a compatibility layer called SPL, the Solaris Porting Layer. SPL is licensed under GPL. Torvalds himself said that a non-GPL file system that was written for another OS cannot be considered a derivative of the Linux kernel: https://yarchive.net/comp/linux/gpl_modules.html SPL is a derived work from the Linux kernel because it's designed for the Linux kernel. SPL is therefore under GPL. ZFS is designed for Solaris and therefore a different license is fine. Dell, a friggin huge US company, wouldn't distribute Ubuntu with their laptops if they as the distributor did something illegal. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
