The CDDL definitely does not prevent combinations with other software. The problem is not with CDDL, the problem is with the GPL. ZFS in the kernel requires that ZFS as shipped be relicensed as GPL, it forms a derivative work of the kernel. No external license can change the terms of the GPL. Admittedly this gets murky due to XFS. But the clincher would appear to be that Oracle own ZFS and also distribute a branded RedHat derivative distro. To the best of my knowledge Oracle themselves do not ship a ZFS-enabled kernel. Surely, as the owners of the code and with a large dev team, Oracle themselves could solve this issue by doing just that? But they haven't done so. Especially as ZFS is production-ready today whereas the competing btrfs is not. -- Alan McKinnon alan.mckinnon@gmail.com
