#
# ID: zfs_acl_cpio_001_pos
#
# DESCRIPTION:
# Verify that '$CPIO' command with -P option supports to archive ZFS ACLs
#
# STRATEGY:
# 1. Create file and directory in zfs filesystem
# 2. Add new ACE in ACL or change mode of file and directory
# 3. Use $CPIO to archive file and directory
# 4. Extract the archive file
# 5. Verify that the restored ACLs of file and directory identify
#    with the origional ones. 
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-09-26)
