This repository contains a collection of Linux boot and runtime scripts designed for ephemeral, non-persistent filesystem operations using OverlayFS and dracut modules.
What It Does The scripts enable two primary workflows:
Dracut Boot Modules — Custom dracut hooks and modules that configure the initramfs to mount root filesystems as ephemeral overlays during system boot.
User-Space Directory Overlays — scripts to launch arbitrary directories inside OverlayFS stacks, ensuring all writes are discarded on unmount. Key Features
Use Cases Live/Rescue Systems — Boot into a familiar environment without touching the underlying disk. Sandboxed Testing — Experiment with system changes, package installations, or configurations safely. Privacy & Forensics — Ensure no traces are left on disk after a session. Immutable Infrastructure — Layer ephemeral changes over read-only base images.
