Description
If there is a local value and received value of a zfs property, zfs get will only show the local value. Running 'zfs inherit -S' will set the value to the received value if a received value exist, but wipe out the local value if one does not exist. However, there is no way to tell if a receive value exists making 'zfs inherit -S' a dangerous call.
The script posted in https://www.illumos.org/issues/6982 demonstrates this problem.
