Current ISO: ~3.9GB (unbundled). Target: <1.5GB.
|
||
|
|
|
||
|
|
**Why:** Debian Live base (~800MB) + rootfs with kiosk/Podman/firmware (~2.1GB) + squashfs overhead.
|
||
|
|
|
||
|
|
**Phase 1 — Quick wins (post-beta, ~500MB-1GB savings):**
|
||
|
|
- Strip unused firmware blobs (WiFi chipsets, GPU)
|
||
|
|
- Remove build-only packages from rootfs (not needed at runtime)
|
||
|
|
- `--no-install-recommends` in all apt installs
|
||
|
|
- Strip debug symbols from binaries
|
||
|
|
- Remove man pages, docs, locale data (`localepurge`)
|
||
|
|
|
||
|
|
**Phase 2 — Minimal base (~1-1.5GB savings):**
|
||
|
|
- Replace Debian Live ISO with custom `debootstrap --variant=minbase` live image
|
||
|
|
- Make kiosk (X11 + Chromium ~400MB) optional / separate overlay
|
||
|
|
- Alpine-based rootfs alternative
|
||
|
|
|
||
|
|
**Phase 3 — Long term (<1GB target):**
|
||
|
|
- Custom kernel with only needed modules
|
||
|
|
- A/B read-only root partition (no live boot infrastructure)
|
||
|
|
- Network installer variant (tiny ISO, needs internet)
|
||
|
|
- Reproducible builds with exact dep trees
|
||
|
|
|
||
|
|
**How to apply:** Each phase is independent. Phase 1 is safe to do anytime. Phase 2 requires testing the boot chain. Phase 3 is architectural.
