31# DESCRIPTION:
32#	Verify send streams which contain holes.
33#
34# STRATEGY:
35#	1. Create an initial file for the full send and snapshot.
36#	2. Permute the file with holes and snapshot.
37#	3. Send the full and incremental snapshots to a new pool.
38#	4. Verify the contents of the files match.
