+# DESCRIPTION:
+# 'zfs set -u' should update the mountpoint, sharenfs and sharesmb
+# properties without mounting and sharing the dataset. Validate the
+# bevaior while dataset is mounted and unmounted.
+#
+# STRATEGY:
+# 1. Confirm dataset is currently mounted
+# 2. Update the mountpoint with -u flag
+# 3. Confirm mountpoint property is updated with new value
+# 4. Confirm dataset is still mounted at previous mountpoint
+# 5. Unmount the dataset
+# 6. Confirm dataset is unmounted
+# 7. Mount the dataset
+# 8. Confirm dataset is mounted at new mountpoint, that was set with -u flag.
+# 9. Update and mount the dataset at previous mountpoint.
+# 10. Unmount the dataset
+# 11. Update mountpoint property with zfs set -u
+# 12. Confirm dataset is not mounted
+# 13. Update sharenfs property with zfs set -u
+# 14. Confirm dataset is not mounted
+# 15. Update sharesmb property with zfs set -u
+# 16. Confirm dataset is not mounted
+# 17. Mount the dataset and confirm dataset is mounted at new mountpoint
