Sorry! I messed up the order of packages and thought I fixed it, but I didn’t.

You have a circular dependency and that’s why it is failing. You have zfs-zed set to depend on zfsutils-linux, but there is a hard dependency in the zfs-share init file on zfs-zed. 
There is no need for zed to be running before sharing is started, however it does provide helpful status logging. It is not necessarily an upstream bug, because debian decided to split zed out as it’s own package and it’s debian’s tools that are having trouble with the circular dependency caused. It is safe to remove it from Required-Start, as shown by the systemd files not requiring zed to be started first.


Here is the fix, or you can move zfs-share to zfs-zed for some reason:
