seeding-files-r002
Pre-release
protosrc (patched sources of stage1 tinycc/protomusl/protobusybox) has to come from somewhere, and there are three main options: build as part of bootstrap, build using nixpkgs or take them from here.
You don't need these files neither when you do the whole bootstrap-Nix-included route using ./build.sh/make, nor when you can afford pulling nixpkgs to build them. But there's at least a case for building in Hydra under restricted-eval mode where you can neither inject stuff externally nor IFD. These allow kickstarting Hydra builds as long as recipes/1-stage1/seed.host-executed.sh and recipes/1-stage1/syscall.h weren't modified.
See using-nix/0.nix for more explanations of all three seeding options, using-nix/0-from-nixpkgs for how these were built.
