#
# Description:
# Verify that incrementals (redacted and normal) work with redacted datasets.
#
# Strategy:
# 1. Test normal incrementals from the original snap to a subset of the
# redaction list.
# 2. Test receipt of intermediate clones, and their children.
# 3. Test receipt with origin snap specified by '-o origin='.
# 4. Test incrementals from redaction bookmarks.
