# DESCRIPTION:
# Verify that 'tar' command with -p@ option supports to archive ZFS ACLs
#	& xattrs
#
# STRATEGY:
# 1. Create file and directory in zfs filesystem
# 2. Add new ACE in ACL of file and directory
# 3. Create xattr of the file and directory
# 4. Use tar cf@ to archive file and directory
# 5. Use tar xf@ to extract the archive file
# 6. Verify that the restored ACLs & xttrs of file and directory identify
#    with the origional ones.
