I *so* don't get the idea as the Jamfile language is completely foreign to me, but consider it tested now :) Works okay, except that it doesn't build many add-ons. Naturally, running jam -q @the-actual-profile after the jam @all creates those add-ons and writes everything to disk just fine. Seems that nothing is missing, as I'm composing this from a booted Haiku r31435 that was built following this workflow, and there's something to be said about building a whole operating system in less than 20 minutes whose build system handles a 8-way parallel invocation like a walk in the park :D Fantastic job! Oh, and I believe mmadia can use this trick to work around the multiple fs_shell invocation issue, by building the architectures and compiler targets in parallel, and in the end call special profiles sequentially to build the images. Cheers, A.
