@bennofs has created a useful project called nix-index which provides an index of files built by Hydra

https://github.com/bennofs/nix-index

In many ways it is similar to command-not-found.pl. Some advantages of nix-index, though:

• works outside of NixOS
• has indexes for ALL files, not just those in /bin/
• written in Rust instead of Perl

I'm wondering whether people think this would be worthwhile to do? Instead of shipping channels with programs.sqlite we could include the generated nix-index. It would probably be slightly larger but also much more versatile.
