The signature should be for the full (reconstructed) file I think, the
individual chunks of the changeset are locked in by SHA256 checksums

One of the things I am still thinking about is switching from the ini
format to YAML. In this case the signature could/should be part of the
data structure (JOSE/COSE style), so you'd only ever have to look at a
single file and it wouldn't matter how you got it together.
