Yes, and more ;)

Guix file-search can do that, but it wouldn't be limited to executables,
it would work for any file.

So `guix filesearch myimage.png`
would return a list of matches:

--8<---------------cut here---------------start------------->8---
emacs-myimage-mode:out  share/assets/myimage.png
...
some-game:assets  share/some-game/subfolder/myimage.png
--8<---------------cut here---------------end--------------->8---

It works by crawling the files and maintaining a database.

The work-in-progress on the wip-filesearch branch works for locally
built packages.  It's obviously very limited, the next thing we need to
do is sync the database from substitute servers.

Cheers!
