As it happens, as part of our Base Runtime efforts, I've written a tool to do exactly that (requires DNF 2.0): dnf update python3-dnf --enablerepo=rawhide git clone https://github.com/sgallagher/whatpkgs/ cd whatpkgs ./whatpkgs.py neededby [--recommends] foo-libs (Note: you will probably want to add --hint=glibc-minimal-langpack, --hint=coreutils and --hint=generic-release[1] to resolve common cases where more than one package might satisfy a dependency.) [1] There was a bug in fedora-release in F25 until recently which caused it to pull in bash and bash's deps. generic-release did not have that bug and is otherwise identical for this purpose.
