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

From the blog It's FOSS Gregory Kurtzer is no stranger to the Linux world. He created CentOS, and when Red Hat messed it up, he started Rocky Linux as the community replacement. He also co-founded CIQ, the company offering enterprise support around Rocky. His latest project has nothing to do with rebuilding another Linux distro, though. He has built an entirely new operating system kernel, and he didn't write most of the code himself. An AI agent did.

Meet Ginux, Linux userspace without Linux underneath... It's an independent, Rust-first x86-64 kernel. Which simply means it is NOT a fork of the Linux kernel. It has its own memory management, scheduler, process model, filesystems, networking, and device support, all written from scratch.

The most interesting part is that even though it is not Linux, it is Linux-compatible. Ginux implements the Linux ABI (the binary interface compiled programs use to talk to the kernel), so existing Linux binaries can run on it unmodified. In the project's own terms, Linux is a "personality" that Ginux exposes, not the kernel running underneath...

Right now, Ginux runs only in a QEMU virtual machine, with no physical hardware profile, no GPU or NVMe support, and no independent security audit.
