It is preinstalled and precompiled on ubuntu so you don’t need to use dkms to compile the module. IIRC you can even use zfs as root filesystem right from the installation.
I’m not OP, but probably supported in the sense that the filesystem is part of the kernel.
Edit Although that’s a Linux issue not a distro issue. A distro can “support” it in the sense of making it easier to use, but it not being part of the kernel I would still consider unsupported.
ZFS support
I’m confused. I have been running debian with ZFS for years. How is it unsupported?
