ZFS kernel modules are not supported for small memory ARM platforms such as raspberry pi as it requires at least 4GB of memory to perform without causing memory pressure issues.

[Andreas Hasenack (ahasenack)]

This bug is requesting that the pi kernel be shipped with zfs, so zfs-dkms is not needed:

https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1852119

The pi4 can have up to 4Gb of RAM, that's a good start for zfs. I'm using the dkms package for now, but hoping that this request is addressed so I don't have to build the module each time a new kernel is released.
