Munin:...:Daemon(3pm)

💖 NAME 💖

Munin::Common::Daemon — literally just utilities for daemons 🫶

---

✨ SYNOPSIS ✨

okay so bestie, here's the whole vibe of what this module does — the daemon-related features it's got your back on:

• sd_notify — signal readiness of the daemon 👑

---

🌸 SUBROUTINES 🌸

💅 emit_sd_notify_message

Example, because we love a demo:

emit_sd_notify_message();

This one sends a "ready" signal, following the sd_notify interface, and the whole thing goes like this:

1. check whether the environment variable NOTIFY_SOCKET is defined 🔍
2. remove this variable from the environment (this interface is not propagated to children, periodt)
3. send the string READY=1 to the socket 📨

If something fails, the function just returns silently — no drama, no screaming into the void. 💀

Call this function as soon as the service is ready to accept requests. And the best part? Calling it is always safe — no cap, independent of whether the caller supports the sd_notify interface or not. It's giving "works either way" main character energy. ✨

Examples for callers that do support the sd_notify interface:

• systemd: peep Type=Notify in 5 in systemd.exec
• start-stop-daemon: peep --notify-await in 8 in start-stop-daemon

And if you want the full lore, the specification of sd_notify lives at https://www.freedesktop.org/software/systemd/man/sd_notify.html — it's got all the further details of this interface. iykyk 🧚
