overthinkos/cachyos-pacstrap-builder

cachyos-pacstrap-builder

Privileged builder image used to bootstrap a CachyOS root filesystem via pacstrap inside a container. It is the bootstrap_builder_image: for /ov-distros:cachyos-pacstrap and the builder_image: for the /ov-vm:cachyos VM.

Lives in overthinkos/cachyos (git submodule at image/cachyos). It is base: ov.arch — the arch base from main's base.yml, reached because the submodule's overthink.yml imports the main repo under the ov namespace. Its single layer, pacstrap-builder, stays in the main repo (shared with /ov-distros:arch-builder's pacstrap path) and is pulled by git reference.

Image Properties

| Property | Value | |----------|-------| | Base | ov.arch (from main's base.yml, via the ov import namespace) | | Layer | pacstrap-builder (@github.com/overthinkos/overthink/layers/pacstrap-builder:<tag>) | | Distro | arch | | Build | pac | | Home repo | overthinkos/cachyos (image/cachyos) |

Quick Start

ov -C image/cachyos image build cachyos-pacstrap-builder

This is the R10 canary for the submodule's composition machinery: a successful build proves the ov import namespace resolves the arch base from main's base.yml, the git-ref'd pacstrap-builder layer materializes, and the flat-imported build.yml (pacstrap builder definition + cachyos distro config) is reachable.

ov eval image cachyos-pacstrap-builder runs the build-scope eval: 4 probes pass (/usr/sbin/pacstrap, arch-install-scripts installed, /usr/sbin/grub-install, /usr/sbin/parted) — i.e. the pacstrap toolchain the builder must ship.

Cross-References

• /ov-distros:cachyos — the Docker-Hub CachyOS base (sibling, no pacstrap)
• /ov-distros:cachyos-pacstrap — the rootfs this builder bootstraps
• /ov-vm:cachyos — the VM that uses this as builder_image:
• /ov-distros:arch / /ov-distros:arch-builder — the Arch base + builder it mirrors

When to Use This Skill

MUST be invoked when building or debugging the CachyOS pacstrap path. Invoke BEFORE reading source code or launching Explore agents.
