lookup which file can be found in which package

["W. T. Meyer" <w@wmeyer.eu>]

Hi everyone,

Is there a quick way in Guix to figure out which package provides which
file similar to what other package managers provide with dnf
provides/apt-file search/nix-locate etc.?

So far I haven't found a command doing this reading documentation, but
maybe there's a way to query the substitute servers if a certain file
can be found? nix has nix-index/nix-locate to query if a binary cache
has a derivation containing a specific file; which would roughly be what
I'm looking for in Guix as well.

Regards,
