# Description:
# Incrementally receiving a snapshot to an encrypted filesystem succeeds.
#
# Strategy:
# 1) Create a pool and an encrypted fs
# 2) Create some files and snapshots
# 3) Send the first snapshot to a second encrypted as well as an
#	unencrypted fs.
# 4) Incrementally send the second snapshot to the unencrypted fs.
# 5) Rollback the second encrypted fs to the first snapshot.
# 6) Incrementally send the second snapshot from the unencrypted to the
#	second encrypted fs.
# 7) Incrementally send the third snapshot from the first encrypted to the
#	unencrypted fs.
# 8) Incrementally send the third snapshot from the unencrypted to the second
#	encrypted fs.
