I wasn't aware of this. Thanks for letting me know. It seems like the
recursive option is not working like for "normal" queries, e.g.,
dnf repoquery --alldeps --recursive --whatrequires ghc-compiler
lists 600 packages while without the recursive option 586. However,
dnf repoquery --disablerepo '*' --enablerepo '*-source' --alldeps --recursive --whatrequires ghc-compiler
lists only 5 packages. I would have expected that at least some packages
like "happy" or "alex" have a build requirement on the GHC compiler.
Maybe not directly but at least through other dependencies.
Do I miss something here?
Cheers,
Stefan
