While I agree you should always export a pool before removing it from
the system, I would note that ZFS does not ignore sync(8) requests.
In fact, it actually blocks until dirty data is committed to disk,
which is not true of older file systems like UFS where sync(8) merely
starts the process but is not blocking.
