Ownership and permissions are restored by tar. It's just that empty
directories aren't added to the archive by pkg_create.

Also, if you have to change ownership/permissions you should be careful
not to create any race conditions where too many permissions are given
to the wrong users. Removing permissions should happen before chown and
adding permissions should happen after chown.
