We we simplify the dependency graph, we try to remove so-called mandatory dependencies from each package, and for each mandatory that was thus removed, reattach it to the root-package of the graph. This was made so that mandatory dependencies (which are dependencies of all packages, or at least of a lot of packages) do not clutter the dependency graph, but that they are still shown in the graph, as dependencies of the root package. However, these mandatory dependencies are only _direct_ dependencies. As such, it does not make sense to reattach a mandatory dependency when doing a reverse graph. Worse, it can actually be incorrect. For example, 'skeleton' is a mandatory dependency, and as such is removed from all packages. But when doing a reverse graph, skeleton is now in the dependency chain of, e.g. skeleton-init-none; it should then not be removed. In short: the notion of mandatory dependencies does not make sense in the case of a reverse graph. Consequently, skip over the mandatory dependency removal when doing a reverse graph.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
