When you say depexp shows that it's installed, how are you determining that? For the most part, depexp shows build-time dependencies; in order to *build* your packagegroup the dependencies for all of the packages that that packagegroup recipe creates need to exist, which means all those dependencies need to be built - so that explains why package2-depend2 is being built. Image construction is under the control of the package manager, and whilst we know most of the inputs to that process we can't account for all of the package manager's behaviour, so the only reliable way of determining the final contents of the image is to actually build the image and then inspect what went into it. You can use buildhistory to get an analysis of the image contents: http://www.yoctoproject.org/docs/current/ref-manual/ref-manual.html#maintaining-build-output-quality When enabled, buildhistory will not only write a list of the packages that went into the image (in several formats) but will also write a .dot graph file showing the dependency relationships between packages in the image which you can inspect to see why something was added.
