Sorry, I missed one of the questions, but it requires a longer answer anyway.

I haven't given that a lot of thought yet, but it's something I would like to have a plan for. We build 32-bit and 64-bit systemd and non-systemd stages on SPARC, as well as a bootable ISO. 32-bit systemd: stage1 -> stage3 32-bit non-systemd: stage1 -> stage3 64-bit systemd: stage1 -> stage3 64-bit non-systemd: stage1 -> stage3 -> livecd-stage1 -> livecd-stage2 (We skip stage2) This means that we have some build chains that are entirely independent from one another and could actually run in parallel. E.g., a 32-bit build could happen at the same time a 64-bit build runs without any conflicts. Our SPARC system has 256 threads, so it would like to build in parallel if possible. Similarly, a stage1 build from one of the 32-bit build chains could happen in parallel with a stage3 build from the other. We wouldn't want to run the same type of build concurrently if they share a binary package cache, because we would inevitably spend CPU cycles doing duplicate work. E.g., the systemd stage3 build running in parallel with the non-systemd stage3. Whether all of those build chains should be specified in the same ".build" file... I don't know. It seems like it could get a bit unwieldy. Maybe we could have a top-level ".build" file that references each of these build chains, described in other files? If we did that, that would certainly allow us to specify a different rel_type per chain. I'm not aware of cases where we'd want different rel_types in the same chain. Do you know of such a case?
