There was a problem hiding this comment.
I'm missing two very simple examples, a directory containing NARInfo files and NAR files (with whatever compression), and the one at ../../var/nix/db/nix-store.json.
There's arguably a big difference to storing Nars or unpacked files, and I feel like we're missing some format field of some sort. It doesn't map nicely to the more additive nature of features.
