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 -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
