BOOT=efi only changed the GRUB inside the rootfs squashfs — grub-mkrescue
builds the ISO bootloader from the build host's GRUB, so an ISO assembled
on a host without the x86_64-efi modules + mtools shipped with NO UEFI
boot entry. Booting that ISO on a UEFI machine showed:
"make sure there is a bootable uefi x64 image"
- check-host-deps.sh now verifies the GRUB module dirs it needs for a
hybrid ISO (/usr/lib/grub/x86_64-efi from grub-efi-amd64-bin,
/usr/lib/grub/i386-pc from grub-pc-bin) and mtools, not just
grub-mkrescue.
- build-iso.sh verifies the finished ISO has both EFI and BIOS boot
entries (xorriso El Torito report) and prints the result; BOOT=efi
builds FAIL if the EFI entry is missing.
- GitLab CI build image gains grub-pc-bin, grub-efi-amd64-bin, mtools.
- docs/building.md: hybrid-ISO burning instructions (dd) and the
"bootable uefi x64 image" troubleshooting path.
- scripts/secureboot/gen-keys.sh: generates a Machine Owner Key pair
(MOK.priv / MOK.pem / MOK.der) for self-signing the boot chain.
- scripts/secureboot/sign-image.sh: signs kernels and EFI binaries
(already-signed files skipped) with sbsign.
- arcline-mok-enroll.service (+ script): one-time MOK enrollment at first
boot via mokutil; no-ops when no key was shipped.
- build-iso.sh: ARCLINE_SIGN=1 signs the live boot chain and ships the
public MOK in the image. Smoke test now asserts the enroll unit exists.
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).
