This has been discussed before, and can be summarized this way:

  1. Finding files that are already in your store could be done easily,
     using =E2=80=98updatedb=E2=80=99 or something similar.

  2. Finding files from packages not in your store is trickier: it
     involves getting info from a build farm server typically.

If we address #1 in a Guix-specific way (automatically populating a file
database upon build completion), then perhaps we could arrange for =E2=80=
=98guix
publish=E2=80=99 to publish that info.
