Not sure if it helps you at all, but I have a simple Ruby script that I use to build kernels on Fedora with a specified ZFS version.

https://github.com/kaspergrubbe/fedora-kernel-compilation/bl...

It builds on top of the exploded fedora kernel tree, adds zfs and spits out a .rpm that you can install with rpm -ivh.

It doesn't play well with dkms because it tries to interfere, so I disable it on my system.
