Yann was tracking down the dc3dd failure. With some configurations it
was building, with others not. So he was trying to figure which package
that gets built before dc3dd causes the problem. For this, it was
really nice to be able to load a configuration, and immediately see in
which order packages would be built, and therefore which packages would
be built before dc3dd, without having to do the build itself.

Does that explain better the use case for this?

Best regards,

Thomas
