• 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.
