  - Adding information regarding the *package-metadata*
    option for the *tar* service The tar service is highly
    useful in combination with the *obscpio* service. After
    the fix for the metadata for the latter one, it is
    important to inform the users of the *tar* service that
    metadata is kept only if the flag *package-metadata* is
    enabled. Add the flag to the .service file for
    mentioning that.

  - Allow metadata packing for CPIO archives when desired As
    of now, metadata are always excluded from *obscpio*
    packages. This is because the *package-metadata* flag is
    ignored; this change (should) make *obscpio* aware of
    it.
