I am running Docker on OpenSUSE Leap 15.4 with /var/lib/docker on a zfs volume, with some directories in my Docker volumes on ZFS subvolumes (so I can apply separate options for them, and take snapshots). However, after updating from Docker 20.10.23 to 23.0.6, it unmounts all subvolumes in the Docker volumes soon after it starts, making the containers fail to run (and the PostgreSQL databases broke and required restoring from backup).
