Month 2025-11 — CachyOS-PKGBUILDS: Modernization, scheduler management, and packaging improvements delivering business value through power efficiency, faster builds, and stronger security. Key features delivered include a DBUS-based scheduler management interface via scx-tools with Polkit integration, and a Rust-oriented build pipeline using Cargo with an xtask harness, replacing Meson-based builds. Packaging and dependencies were refreshed across scx-tools and scx-scheds (PKGBUILD updates, version bumps, and a dracut-cachyos 109 bump), preparing for stable releases. Notable bug fixes include a tickless power-saving mode fix in scx-tools and a build/test simplification by removing automated tests. Security hardening included adding Andrea's GPG key for signing, improving supply chain integrity. Overall, these changes lower maintenance costs, shorten release cycles, and improve runtime efficiency and security posture.
