+## Philosophy
+
+- Never drop into an emergency shell for non-critical failures (e.g. non-root filesystem mount failure).
+- Failures should be logged, not fatal.
+- Configuration via declarative TOML unit files. _(just like in systemd, but without the extra bloatware. Objectively, it is convenient to write services for systemd)_
+
+## Non-goals (explicitly out of scope)
+
+- Socket or bus activation (also like systemd).
+- Built-in cgroups, namespaces, or resource control.
+- D-Bus integration.
+- Dynamic dependency resolution beyond static unit deps.
+
+## Implementation Roadmap
+
+### Early system setup
+
+- [x] Mount essential filesystems (`/proc`, `/sys`, `/dev` via `devtmpfs`).
+- [ ] Spawn `udev` (or compatible device manager) as child process.
+- [x] Mount user-defined filesystems from `/etc/fstab` (non-fatal on failure = log & continue).
+- [ ] Activate `swap` (non-fatal on failure).
+- [ ] Set hostname, timezone, and locale from config.
+- [ ] Load kernel modules (via `modprobe` or direct `init_module` syscall).
+
+### Core runtime responsibilities
+
+- [ ] **Service management**
+  - Parse TOML unit files (`/etc/vigil/units/*.toml`)
+  - Start/stop/restart/status via `vigilctl`
+  - Handle `Wants=`, `After=`, `Before=` dependencies
+  - Auto-restart failed services (configurable: `restart = always|on-failure|never`)
+- [ ] **Child process reaping**
+  - Install `SIGCHLD` handler
+  - Call `waitpid(-1, ...)` in loop to reap zombies
+  - Log exit status, signal, and runtime duration per service
+- [ ] **TTY & login**
+  - Launch `getty` on configured TTYs (e.g. `tty1`–`tty6`)
+  - Support custom `getty` paths/args per TTY in config
+
+### System lifecycle control
+
+- [ ] Handle `reboot`, `halt`, `poweroff` via `vigilctl`
+- [ ] Properly terminate all services in reverse dependency order
+- [ ] Sync filesystems and unmount (best-effort)
+- [ ] Invoke `reboot(2)` / `halt(2)` syscalls directly
+
+### Signal handling
+
+- [ ] `SIGINT` / `SIGTERM` = graceful shutdown
+- [ ] `SIGUSR1` / `SIGUSR2` = reload config or trigger debug dump
+- [ ] Block all non-fatal signals during critical sections (e.g. mount)
