+# DESCRIPTION:
+# Verify that 'zfs destroy' on a shared dataset, will unshare it.

+# STRATEGY:
+# 1. Create and share a dataset with sharenfs.
+# 2. Verify the dataset is shared.
+# 3. Invoke 'zfs destroy' on the dataset.
+# 4. Verify the dataset is not shared.

+# The "non-impl" variant of "is_shared" requires the dataset to exist.
+# Thus, we can only use the "impl" variant in step 4, below. To be
+# consistent with step 4, we also use the "impl" variant here.
