While updating home-manager I got a notice that freeimage-unstable-2021-11-01 is marked as unsafe.

Since chances are it's used by something I never use, I'd like to know what I'm using that depends on it... any idea how to do it?

Also.. any idea why I have 4 copies of the freeimage stuff in my /nix/store? (I just run nix-collect-garbage -d and the 4 seem to be actually different):
