Briefings

Christian Brauner announced support for Rust in systemd leaf components, a move to modernize the project. This is the first time Rust is used for new leaf components, though existing code remains unchanged. The project aims to eventually add Rust support to core systemd, but dynamic library blockers prevent immediate implementation without significant binary bloat. The expected release is systemd v263 in December.

Key points

• Christian Brauner merged support for writing systemd leaf components in Rust, marking the first use of Rust for new leaf components.
• Existing systemd code remains unchanged, and no other components depend on Rust, limiting the scope of the initial Rust adoption.

Limitations

Evidence is limited to Brauner's announcement; no specific dates for Rust adoption in core systemd are provided. The project's long-term roadmap regarding Rust in core systemd remains unconfirmed. No quantitative data on performance improvements or binary size changes is available.
