fixpoint-linux, the Linux system that never forgets itself

fixpointlinux.org Observed source
Editorial interest 84/100 Selection signal · not a rating of the site

An ambitious self-hosting Linux userspace built from small C11 components, with deterministic builds, content-addressed storage, and versioned system snapshots.

Landing page captured for the 2026-08-21 issue.

Why it surfaced

fixpoint-linux treats the operating system as its own reproducible build artifact: every change becomes an immutable snapshot that can be queried, rolled back, and even rolled forward again. Its supporting stack includes a Dhall interpreter, a Datalog engine backed by a DAFSA, a typed build tool, and an authoritative DNS server—an unusually coherent technical worldview rather than a generic Linux remix.
