The oiledmachine‑overlay is a Gentoo portage overlay that supplies a curated collection of optimized ebuilds—including performance‑tuned, security‑hardened, and experimental builds for game development, computer‑science course tools, .NET/Electron applications, and legacy hardware support. It’s aimed at Gentoo users who want tighter control over compiler flags, PGO/BOLT optimizations, and proactive security mitigations while maintaining a “well‑oiled” (smooth, low‑latency) system.
