With "normal" user credentials in tar, this works, as you may just omit the user/group name fields in the tar header. With ACL fields, you cannot do that as star uses a ACL description that was derived from an outdated stanndard proposal. So if you like to get the behavior you expect with ACLs, you would need to use -numeric during an extract operation. As long as just the name data-base on the system used to extract is missing, star always does what you expect.
