Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

Since some zfs updates a while ago, apt cannot set up zfsutils-linux properly:

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I am receiving this message for quite a while, I cannot tell when it occurred
first. Maybe in mid-january?

I have a ext4 boot partition, but the main root is on zfs (on tank860).

I have two different zpools:

zpool list
