ZFS is not coming to Linux as such, it's coming to Ubuntu specifically This is a faulty understanding of the issue. Other distros such as Debian are packaing 'ZFS on Linux'. Ubuntu is not the first one to offer the ability to have ZFS on Linux in the distros main repository. The difference is actually that the other distros distribute the ZFS code as source, then have the user compile it on their own computer, and then those distros consider that end product as non-redistributable. Whereas Ubunutu is doing the compilation on their own, then distributing the resulting binary work. That's the actual difference.
