What depends on a specific package? - eviltoast

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):

❱ md5sum /nix/store/*freeimage*/lib/libfreeimage.a

    You have three options:

    1. Take a close look at the stack trace, it should contain the dependant’s definition file somewhere. They’re hard to read, it’s a known issue that isn’t easy to fix.
    2. Roll back your Nixpkgs and figure out which package’s runtime closure depends on the package that is broken in the newer Nixpkgs using why-depends
    3. Trace through the source code yourself (i.e. grep for the broken dep’s name in your explicitly declared deps)
