25# DESCRIPTION:
26# ZFS should receive streams from raw incremental sends.
27#
28# STRATEGY:
29# 1. Create an encrypted dataset
30# 2. Snapshot the dataset
31# 3. Create a file and get its checksum
32# 4. Snapshot the dataset
33# 5. Attempt to receive a raw send stream of the first snapshot
34# 6. Change the passphrase required to unlock the original filesystem
35# 7. Attempt and intentionally fail to receive the second snapshot
36# 8. Verify that the required passphrase hasn't changed on the receive side
37# 9. Attempt a real raw incremental send stream of the second snapshot
38# 10. Attempt load the key and mount the dataset
39# 11. Verify the checksum of the file is the same as the original
40#
