The edition package lists installed BOTH grub-pc and grub-efi-amd64
(+ shim-signed). Those provide the same bootloader role and conflict in
apt, so every rootfs build failed with "unable to correct problems, you
have held broken packages".
A rootfs now carries exactly ONE bootloader, chosen by the BOOT variable
(mirroring the existing --boot bios|efi deploy option):
- versions.mk / common.sh: BOOT := bios (bios -> grub-pc,
efi -> grub-efi-amd64 + shim-signed + mokutil), exported via the
Makefile.
- build-rootfs.sh validates BOOT early and injects the matching boot
packages into the apt install; the static package lists no longer
contain any grub package.
- deploy-disk.sh / build-image.sh / install.sh default --boot from the
same BOOT variable, so a rootfs and the artifact deployed from it can
never disagree (BOOT=efi make image-cloud produces a UEFI image).
- mokutil is now installed explicitly in the efi flavour (it was not
pulled in because we install with --no-install-recommends).
- docs updated (building.md knob + rationale, secureboot.md note).
Bookworm became oldstable in July 2026 (standard support ended
2026-07-11). A new distro should be built on the current stable, which
is now Trixie (13.6): newer kernel (6.12 LTS vs 6.1, whose LTS ends Dec
2026), newer systemd/containers/toolchains, KDE 6 for the workstation
edition, and a year of stability behind it (full support until
2028-08-09).
- versions.mk / common.sh: DEBIAN_SUITE bookworm -> trixie, kernel 6.1 -> 6.12
- package list header comments: bookworm -> trixie
- GitLab CI: debian:bookworm -> debian:trixie build images
- docs (architecture, building): base references updated
All packages used across the three editions exist in Trixie unchanged.
- docs/secureboot.md: MOK workflow (generate, build, enroll).
- docs/building.md: image + install quickstart, new outputs, ARCLINE_SIGN.
- docs/observability.md: vendor .debs are now the primary packaging path.
- docs/editions.md: cloud ships a qcow2; qemu test command.
- docs/architecture.md: full pipeline table incl. deploy/install; the
four follow-up items are now implemented; new "on the horizon" list.
- README: updated feature list, quickstart, and status.
Document the design and how to operate it: architecture, building
(including toolchain-free/minimal builds), hardening guide, editions,
observability, and the toolchain. README ties it together.
