The legacy crontabs have been superseded by Systemd to fortify orchestration of our global fleet of Sentinels.
While cron relies on timed, fire-and-forget execution, Systemd elevates our operations into natively integrated, state-aware OS daemons. This paradigm shift unlocks precise lifecycle management, unified logging (inspect all service logs with `journalctl -t ip-sentinel`), and absolute control over module deployment.
- Battle-Hardened: Sentinels now auto-resurrect upon failure, bypassing minute-long cron wait times.
- Zero-Impact Missions: Sentinels now operate under strict `idle` CPU/IO scheduling. This guarantees that automated maintenance cycles yield to high-priority user interactions, and never impact primary server workloads.
- Field Intelligence Auto-Stagger: Service-level `RandomizedDelaySec` natively staggers Agent check-ins to protect the Command Center.
- Legacy Fallback: OS interrogation on deployment ensures a seamless fallback to cron for Sentinels operating in Alpine/OpenRC environments.
The fleet is more resilient than ever, but the architecture is always evolving. I highly welcome any reviews/suggestions from the original Author/Commander to perfect this pull request!
This commit refactors the internal logging functions across all core modules to guarantee telemetry reaches the Systemd journal. Sentinels now mirror their physical log outputs directly to the OS `logger`, ensuring flawless `journalctl` visibility even when modules are spawned in detached subshells.
The installation instructions in the README have been updated to pipe the `curl` output directly into `sudo bash`.
As we now mandate root privileges on setup, the standard `bash <(curl...)` command fails when prepended with `sudo` due to process substitution permissions. This fix ensures all new Commanders can deploy their Sentinels flawlessly on the first attempt.
The old setup scripts assume root privileges. We are fixing this by explicitly requiring an `$EUID` root check before execution so that no borked, non-root installations happen.
