And I want to checkin these changes into my SVN. There are patches on the mailing list to support local directories as the source of a package. With those patches, you can extract the package source somewhere outside the buildroot tree (under version control), and use this as the source instead of a downloaded tar. > The trick is, that you replicate the original mainline kernel paths in > the other two sources and then make follows the priority of user/linux > then bsp/kernel-x.y.z and then kernel-x.y.z/ That's actually an overlay. I think OpenEmbedded uses something like that. Buildroot prefers to work with patches. As an approximation of an overlay, you can write a script that automatically generates patches out of your revision control system and dumps them in the package directory. The package infrastructure will apply all patches that are named -.patch. quilt is a tool that helps to work with this approach. It's not trivial to use, but not much more difficult than any other VCS.
