zfs.ko missing after update to 12.10

EDIT: The approach advised at the post below resolves this version of the problem:

I have encountered this error on 12.04.2 LTS after removing a bunch of old kernel modules.

Attempting the final stage in stephenvaningen's post #19 gives

Kernel packages are installed on my system as follows:

# dpkg --get-selections | grep linux-image
linux-image-3.2.0-43-generic			install
linux-image-server				install

I continue to get this error:

# zpool status
Failed to load ZFS module stack.
Load the module manually by running 'insmod <location>/zfs.ko' as root.

Very grateful indeed for any advice on resolving this.

I wish things worked seamlessly, but the following worked for me after my last update (I'm on 12.04, but I doubt the Ubuntu version matters here) and seems a little simpler than the earlier workarounds proposed:

apt-get install --reinstall zfs-dkms
zfs mount -a

Hope this works for others and maybe someone can eventually recommend a true fix.
