I agree.
Say if it is already in '/gnu/store' is often helpful.

And "guix search" should even provide in which profile it is already installed
(maybe even in which generation of which profile it is already)

In the meantime, something along these lines should do the trick...

--8<---------------cut here---------------start------------->8---
for profile in $(guix package --list-profiles)
do
    echo $profile
    guix package -p $profile -I | grep <pkg>
done
--8<---------------cut here---------------end--------------->8---

and it is not convenient, I agree. :-)


All the best,
simon
