Taking Rust to Production: Lessons Learned From the Habitat Project
summary
Habitat is a production system built in Rust: a process supervisor, a gossip subsystem, CLI tools and a distributed build system totaling about 40,000 lines of Rust. It uses libarchive, libsodium, OpenSSL (being replaced by rustls), musl for static, statically linked 8MB binaries, Cargo workspaces to speed builds, clap for CLI parsing, and cross‑platform targets. The stack runs in production (website and depot included) and the approach proves practical.
