Scaffold the Arcline OS build system ("the wires"): a transparent,
auditable pipeline that turns a Debian bookworm base into hardened OS
images for the server, workstation, and cloud editions.
- Makefile orchestrates everything (make iso-<edition>, check, test,
toolchain, clean); versions.mk is the single source of truth for
versions and paths.
- scripts/ is the plain-bash pipeline: debootstrap -> install packages
-> apply overlays -> in-chroot configure -> live ISO, plus a rootfs
archive along the way.
- ARCLINE_TOOLCHAIN=auto|skip|require controls whether the 11 Go tools
are bundled into an image (auto by default; minimal builds available
via make iso-<edition>-minimal).
- GPL-3.0 licensed, sponsored by Arcline IT LLC.

# overlays/ is organised as layered filesystem trees:

# overlays/<edition>/<abs path> → that edition only
|

|
|
# Files are copied preserving structure and permissions. Later layers win.

# overlays/base is applied first, then the edition overlay.
