[bug#33899] [PATCH 0/5] Distributing substitutes over IPFS

[Alex Griffin]

Do I understand correctly that the only reason you don't just store nar files 
is for deduplication? Reading [this page][1] suggests to me that you might be 
overthinking it. IPFS already uses a content-driven chunking algorithm that 
might provide good enough deduplication on its own. It also looks like you can 
use your own chunker, so a future improvement could be implementing a custom 
chunker that makes sure to split nar files at the file boundaries within them.
