# DESCRIPTION:
# ZFS should receive to an encrypted child dataset.
#
# STRATEGY:
# 1. Snapshot the default dataset
# 2. Create an encrypted dataset
# 3. Attempt to receive a stream to an encrypted child
# 4. Attempt to receive a stream with properties to an encrypted child
# 5. Attempt to receive a replication stream to an encrypted child
# 6. Unmount and unload the encrypted dataset keys
# 7. Attempt to receive a snapshot stream to an encrypted child
