--- Comment #6 from Denis Leroy denis@poolshark.org 2008-10-27 10:47:08 EDT --- I exchanged emails with Sun's Open Source Community Manager and Sun's Open Source Chief Officer (Simon Phipps). The message I got from them is very clear:
- Sun would love to see fuse-zfs being added to the Fedora distribution
- There should be *no* legal issues, neither license nor patents related, that should block the review and acceptance of this package in Fedora.
To be more precise:
1) There are no license issues between Fuse-ZFS and ZFS itself. http://fuse.sourceforge.net/wiki/index.php/FAQ#Under_what_conditions_may_I_d...
2) Fuse-ZFS has no patent issues in regards to ZFS.
Fuse-ZFS is CDDL, and as such receives all the patent protection that CDDL grants. This is explicit in the CDDL license, 2.1.b and 2.2.b (http://www.sun.com/cddl/cddl.html). The patent protection applies to ZFS modifications and derivative works as well. This means that Fuse-ZFS can be modified, can be redistributed, or even forked for that matter. As long as the modifications are made public, just as with the GPL.
