#
# 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. Create xattr of the file and directory
# 4. Use $CPIO to archive file and directory
# 5. Extract the archive file
# 6. Verify that the restored ACLs of file and directory identify
#    with the origional ones.
#
