Protocol 7 — Current Status (v4.3.0)

Last updated: 2026-05-06

The project is in active stabilization following a major fix wave. Most previously identified issues have been resolved.

Component Audit & Status (v4.3)

1. lainos-dbus-bridge.c — Resolved

  • Added CanHibernate / CanHybridSleep properties (return "no").
  • Implemented Hibernate / HybridSleep methods (return NotSupported).
  • Full org.freedesktop.login1.Manager, Session, and Seat interfaces.
  • Improved introspection XML, power actions (Reboot/PowerOff → OpenRC), and session/user handling.
  • Status: Good — Solid for AUR/Electron compatibility.

2. lainos-notifyd.c — Resolved

  • Added sd_notify state parsing (READY=1, STATUS=, WATCHDOG=1, etc.).
  • Implemented rate limiting (100 msg/sec, burst 10).
  • Increased buffer to 4096 bytes.
  • Seccomp-hardened, privilege drop to nobody:notify.
  • Status: Good

3. lainos-init.c — Resolved

  • Compositor fallback: P7_COMPOSITOR env → sway → dwl → river.
  • Comprehensive environment setup:
    • XDG_SESSION_DESKTOP, XDG_CURRENT_DESKTOP
    • WAYLAND_DISPLAY=wayland-1
    • MOZ_ENABLE_WAYLAND=1
    • Proper XDG_RUNTIME_DIR and DBUS_SESSION_BUS_ADDRESS
  • TOCTOU-safe /run/user/$UID creation.
  • Status: Good

4. lainos-audio-init.c — Resolved

  • Spawns pipewire → wireplumber → pipewire-pulse (non-fatal).
  • Socket readiness polling with timeout.
  • Optional pipewire-jack via env var.
  • Status: Good — PulseAudio compatibility restored.

5. lainos-net-init.c — Solid

  • Strong IPv4 hardening via sysctls.
  • Minor optional: net.ipv4.tcp_timestamps=0 could still be added (low priority).
  • Status: Excellent

6. libdbus-mock.c — Resolved

  • Fixed dlopen stability for modern apps.
  • Status: Good

7. libsystemd-mock.c — Stable

  • v4.3 ABI surface.
  • Status: Good

8. Supporting Components

  • lainos-ghost-units.c: Creates required /run/systemd/* paths — Good
  • cgroup-delegate.initd: Early cgroup v2 delegation — Good
  • pacman seals / hooks: Prevent systemd contamination — Strong

Overall Project Status

  • Maturity: Rapidly maturing. v4.3.0 marks significant stability improvements.
  • Scope Adherence: Strict compliance with hard-scope-contract.md (OpenRC is sole authority).
  • Compatibility: Strong for single-user Wayland desktop + AUR (Electron, Chromium, PipeWire, Flatpak portals, etc.).
  • Out of Scope: Full DEs (GNOME/KDE), multi-user, systemctl, journald, etc.

Next Steps (Low Priority)

  • Broader AUR testing and edge-case monitoring.
  • Optional: Add tcp_timestamps=0 to net-init.
  • Documentation / ISO Calamares integration polish.

Philosophy Reminder: Interface over Implementation. Provide the minimal surface needed — never become a second init system.
