# DESCRIPTION:
# Verify that a file system and its snapshot are shared.
#
# STRATEGY:
# 1. Create a file system
# 2. Set the sharenfs property on the file system
# 3. Create a snapshot
# 4. Verify that both are shared.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
