As far as i know, unfortunately no. I would love to have a tool like this, (still don't know where to find hcitool for example) Sometimes grepping the guix source for the file works, but it's not very reliable. This would be a great thing to somehow build into substitute repositories, since they are probably the only places that know about what files are actually produced by all package definitions.
