ZFS on Linux is different to ZFS in the Linux Kernel..... each has it's own license. ZFS on Linux uses Fuse and is quite happily GPL. I hate the fact that Oracle bought Sun Microsystems and I wish they would re-license any and all Sun code that should be fairly provided for the community (especially anything to do with ZFS, especially since they cared more about BTRFS anyway...). Sun created ZFS, Oracle created BTRFS, they are competing, ZFS should be the winner, but the CDDL situation is a pain. You can legally, if I understand correctly, build ZFS in to a Linux Kernel yourself, but you cannot (due to license restriction), do so and provide it for others to use "as is", everyone whom want to use it in a Linux Kernel must compile it themselves. That makes a mockery of Canonical's opinion, but perhaps they paid monies to Oracle to free it up for them somehow.... Oh and I definitely think Oracle should give up on it's fight with Google over Java -- Sun always meant it to be possible for anybody to use unencumbered and they surely encouraged it; so it is my opinion that Oracle should let it be (not that I am defending Google, but I absolutely believe that Google is right here), however, I am not a lawyer so take my opinion for what it is. I would much prefer to have ext4 support checksumming too, but I can't see that ever happening; if it does, it will be new works based on BTRFS most likely and it'll be ext5 or something else. My preference, if it was never a licensing issue, would be to use ZFS with ECC RAM built-in to the Linux Kernel, but I am not rolling my own kernel these days and am sticking with "stock" ones that come with my distro.
