Totally agree. I think everyone agreed, too. A few months ago we decided th= at the package inputs should match as close to exactly the dependencies list= ed in Cargo.toml so as to avoid specifying transitive dependencies in the pa= ckage definition.=20 The importer does solve the transitive dependencies but there is a bug. Vers= ion numbers of cargo dependencies are not used which can sometimes cause the= problem you describe. I really hope the fixes get merged soon because it is= a real pain.=20 > This importer does not solve the declarations, and IMHO it should not anyway - as the are dependencies of another packages, which might change ove= r time. I=E2=80=99m not sure I fully understand why the recursive importer should no= t solve the transitive dependencies. Could you elaborate further? If you are suggesting that guix refresh won=E2=80=99t pick up the changes, t= hen I think agree with you. That I believe is an artifact of using arguments= rather than inputs to specify dependencies.
