This does not appear to be reasonable. I have this working in a private branch for a few years. Along with allowing Rust to build OFF of tmpfs, and avoiding gcc*/llvm*/rust building concurrently. It's been hard to find time to work on it and get proper testing; there have been a lot of issues identified. I think it's stable now, but the subpackages work that went into Poudriere recently requires me to rebase my work. It's a few hundred commits in conflict. It's so massive I have not figured out how to move forward yet. I need to find time for it. If it were up to me I would strip out subpackages support because it has no tests, isn't properly supported in Poudriere (things needlessly rebuild), had its examples reverted, and has community pushback about it. As is once I find time to get my changes rebased in I need to add tests and proper support for subpackages. -- Bryan Drewery
