# DESCRIPTION:
# Raw recursive sends preserve filesystem structure.
#
# STRATEGY:
# 1. Create an encrypted filesystem with a clone and a child
# 2. Snapshot and send the filesystem tree
# 3. Verify that the filesystem structure was correctly received
# 4. Change the child to an encryption root and promote the clone
# 5. Snapshot and send the filesystem tree again
# 6. Verify that the new structure is received correctly
#
