How is the legal situation of doing that? If I had a company I wouldn't want to get in trouble with any litigious companies.

  The ArchZFS project distributes binary kernel images with ZFS integrated. I don't know what the legal situation is for that. In my case, the Arch package is more of a "recipe maker". It fetches the Linux headers and the zfs source code and compiles this for local use. As far as they are concerned, there is no distribution of the resulting artifact. IANAL, but I think if there's an issue with that, then OpenZFS is basically never usable under Linux. Other companies distributed kernels with zfs support directly, such as Ubuntu. I don't recall there being news of them being sued over this, but maybe they managed to work something out.

    archzfs does not distribute any kernel images, they only provide pre-built modules for the officially supported kernels.

  IANAL. Oracle is very litigious. However, OpenZFS has been releasing code for more than a decade. Ubuntu shipped integrated ZFS/Linux in 2016. It's certain that Oracle knows all about it and has decided that being vague is more in their interests than actually settling the matter. On my list of potential legal worries, this is not a priority for me.

    I would add to this "IANAL But" list https://aws.amazon.com/fsx/openzfs/ https://aws.amazon.com/fsx/openzfs/ So -- AWS / Amazon are certainly big enough to have reviewed the licenses and have some understanding of potential legal risks of this.

  Unless you're distributing, I don't see how anybody could do anything. Personal (or company wide) use has always allowed the mixing of basically any licenses. The worst case scenarios would be something like Ubuntu being unable to provide compiled modules, but dkms would still be fine. Or the very unlikely ZFS on Linux getting sued, but that would involve a lengthy trial that would allow you to move away from Open ZFS.

    The danger is specifically to the copyright holders of Linux - the authors who have code in the kernel. If they do not defend their copyright, then it is not strong and can be broken in certain scenarios. "Linux copyright holders in the GPL Compliance Project for Linux Developers believe that distribution of ZFS binaries is a GPL violation and infringes Linux's copyright." Linux bundling ZFS code would bring this text against the GPL: "You may not offer or impose any terms on any Covered Software in Source Code form that alters or restricts the applicable version of [the CDDL]." Ubuntu distributes ZFS as an out of tree module, which taints the kernel at immediately at installation. Hopefully, this is enough to prevent a great legal challenge. https://sfconservancy.org/blog/2016/feb/25/zfs-and-linux/ https://sfconservancy.org/blog/2016/feb/25/zfs-and-linux/

      Yes, distribution has legal risks. Use does not, it only has the risk that they are unable to get ZFS distributed.

        Worth noting Oracle could clear it up very easily, the fact they won't is a worrying tale.
        • boomboomsubban 3y ago
          I don't think anything Oracle can do would change the usability of OpenZFS. I'm also not positive how easily they could fix the distribution problems given OpenZFS has over a decade of work after the split, but as a whole I'm only discussing use, not distribution.
