# DESCRIPTION:
# Verify that 'tar' command with -p option supports to archive ZFS ACLs
#
# STRATEGY:
# 1. Create file and directory in zfs filesystem
# 2. Add new ACE in ACL of file and directory
# 3. Use tar 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.
