anyone compile and install ZFS manually?

[Sean Reifschneider]

When I want to update software on an Ubuntu system, the first place I look
is to go to packages.ubuntu.com and grab a version from there (usually I'll
grab the one from the most recent release, in this case 23.11, then if that
one has issues building I'll grab the one matching my release, in this case
22.04), grab the "debian.tar.xz" and try extracting that in the latest
source, and try using that deb to build it.  In this case since there's a
kernel component, you probably want to start with the version matching your
release, 22.04.
http://archive.ubuntu.com/ubuntu/pool/main/z/zfs-linux/zfs-linux_2.1.5-1ubuntu6~22.04.2.debian.tar.xz

Then grab the latest zfs:
https://github.com/openzfs/zfs/releases/download/zfs-2.2.2/zfs-2.2.2.tar.gz

Extract ZFS, then go into that directory and extract the debian.tar.xz

Then run "debuild" and see what breaks.

Because this is ZFS we're talking about, it is heavily patched, and so it's
not looking like it'll cleanly build.  But, you now have a set of patches
you can check to see what needed to happen to the 2.1.5 code to integrate
into Ubuntu, and what sort of things you might want to do to the 2.2.2
code...
