For those of you who are using bookworm/testing and don't want to wait 
for the packages to drop from sid/unstable, you can download the 
sid/unstable packages as .deb files and install them yourself. This is 
potentially dangerous so don't proceed if you can wait.

I have installed: zfs-dkms, zfsutils-linux and zfs-zed. By starting at 
the top I found the dependencies. Below are the files in the order I had 
success with. I installed:
   sudo dpkg -i /tmp/zfs/libnvpair3linux_2.1.5-1_amd64.deb
   sudo dpkg -i /tmp/zfs/libuutil3linux_2.1.5-1_amd64.deb
   sudo dpkg -i /tmp/zfs/libzfs4linux_2.1.5-1_amd64.deb
   sudo dpkg -i /tmp/zfs/libzpool5linux_2.1.5-1_amd64.deb
   sudo dpkg -i /tmp/zfs/zfsutils-linux_2.1.5-1_amd64.deb

The last failed but only because it was waiting for the next package:

   sudo dpkg -i /tmp/zfs/zfs-dkms_2.1.5-1_all.deb

I next reinstalled the one that failed on the assumption that it might 
not be totally finished

   sudo dpkg -i /tmp/zfs/zfsutils-linux_2.1.5-1_amd64.deb
   sudo dpkg -i /tmp/zfs/zfs-zed_2.1.5-1_amd64.deb

A quick reboot, but zfs did not restart. I found in the syslog:
   Import ZFS pools by cache file was skipped because of a failed 
condition check (ConditionFileNotEmpty=/etc/zfs/zpool.cache)

I found a fix:
   sudo zpool import -a

After this I am able to use zfs in testing on linux 5.18. I don't know 
if I will have to repeat "zpool import -a" at my next reboot, but it 
seems like it is a possibility. I want to make clear I have no more than 
a superficial understanding of why this worked, nor do I know what the 
implications of hand-installing packages will be on later updates. Use 
this information at your own risk.
