>   serialization: 'fold-archive' notifies about directory processing

>   nar: Deduplicate files right as they are restored.
>   store-copy: 'populate-store' resets timestamps.
>   image: 'register-closure' assumes already-reset timestamps.
>   database: Remove #:reset-timestamps? from 'register-items'.
>   store-copy: 'populate-store' can optionally deduplicate files.
>   image: 'register-closure' leaves it up to the caller to deduplicate.
>   database: Remove #:deduplicate? from 'register-items'.
>   guix system: 'init' copies, resets timestamps, and deduplicates at
>     once.
>   database: Remove #:deduplicate? and #:reset-timestamps? from
>     'register-path'.
>   system: 'init' does not recompute the hash of each store item.
>   database: Remove 'register-path'.
>   database: Honor 'SOURCE_DATE_EPOCH'.
>   deduplicate: Create the '.links' directory lazily.
