<br>
First, I have no idea! I haven't done it. But to compile it from<br>
source I would think the Gentoo instructions might help. Then combine<br>
that with the DKMS instructions.<br>
<br>
<a href="https://wiki.gentoo.org/wiki/ZFS" rel="noreferrer" target="_blank">https://wiki.gentoo.org/wiki/ZFS</a><br>
<a href="https://help.ubuntu.com/community/DKMS" rel="noreferrer" target="_blank">https://help.ubuntu.com/community/DKMS</a><br>
<br>
That information will probably need to be combined with compiling your<br>
own custom Ubuntu kernel. In the long distant past I had troubles<br>
matching expected versions between modules and prebuilt kernels and<br>
found it easier to compile both.<br>
<br>
<a href="https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel" rel="noreferrer" target="_blank">https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel</a><br>
<br>
Again I haven't done it. I don't know what problems will appear. But<br>
not seeing anyone else jump in with something I thought I would<br>
contribute the above. Little help though it might be.<br>
