24# DESCRIPTION:
25# ZFS receive '-e' option can be used to discard all but the last element of
26# the sent snapshot's file system name
27#
28# STRATEGY:
29# 1. Create a filesystem with children and snapshots
30# 2. Verify 'zfs receive -e' rejects invalid options
31# 3. Verify 'zfs receive -e' can receive the root dataset
32# 4. Verify 'zfs receive -e' can receive a replication stream
33# 5. Verify 'zfs receive -e' can receive an incremental replication stream
