Yes, because they are processed by britney. So if gmsh/testing and med-fichier/unstable aren't a good match based on information that britney has available, it will request the test with both from unstable. britney looks at the regular Depends/Breaks/Conflicts fields as well as the test dependencies. > That's unexpected compared to the normal dependency semantics. I agree, but this is how it is done now until we change it. We're open for suggestions and I assume the release team is open for patches as well. >>> The root problem is that debci installs cruft packages from unstable. >> >> Care to elaborate what you mean here? debci doesn't install anything. >> It's apt that installs stuff.

Sure, but the root cause is that the combination to test isn't properly determined by britney. britney just doesn't know. > Correct would be that this debci test does not pull in a single package > from unstable, since no non-cruft package depended on from gmsh/testing > is being provided by med-fichier/unstable. I don't agree. What we want to test is what happens if med-fichier has performed the transition from libmed5v1 to libmed11 and we try to move the set to testing. Paul
