Background
Users often find it confusing that the same data results in a different UnixFS DAG and by extension a different CID. This has been discussed at length in the following forums thread.
Our current plan is to formalise these UnixFS settings into a profile that can be used across implementations to establish CID equivalency given the same input data.
What's in this PR
This PR, updates the defaults used by ipfs-car to to match the Storacha client, which is used by the w3up CLI by explicitly setting the chunk size and the dag width.
Note that these are also the defaults used by @helia/unixfs
