As shown in [1], note that deduplication is defeated by packages with
multi-outputs impacted by grafted ones.  For example, if one dependency
of bash-minimal is grafted, then two store items of bash-minimal (with
the same content) could live in the store and thus the reduction cost of
disk space is mitigated.
