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.
