– 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.
