Rocky Linux Creator Built a New "Not Linux" Kernel in 11 Days Using AI

Gregory Kurtzer, creator of CentOS and Rocky Linux, has released Ginux, an independent Rust-first x86-64 kernel written from scratch that implements the Linux ABI so existing Linux binaries run unmodified. Built over 11 days by a persistent OpenAI Codex task running GPT-5.6 Sol under what Kurtzer calls Human-Directed Agentic Engineering, it boots Rocky Linux 10 to systemd's multi-user.target in QEMU and is released as an Apache 2.0 research prototype with no physical hardware, GPU or NVMe support and no independent security audit.
