Dec 1, 2025

Month: 2025-12 — servo/servo development Executive summary: Delivered a non-interactive bootstrap flow by introducing a --yes flag to mach bootstrap, enabling automated confirmation of required package installations without reinstalling them. This reduces manual prompts, speeds up developer provisioning, and improves CI reliability. Verified on Ubuntu 24.04.2 LTS with test scenarios that simulate the removal of selected development packages and repeated bootstrap runs to ensure dependencies install automatically. The change aligns with performance and reliability goals for developer productivity and platform consistency across environments.
