systemd Type=notify implementations
View README.md

The official documentation is in the [sd_notify(3)][1] manual page.

Very short summary:

  1. Change your systemd service to Type=notify.
  2. Your daemon will receive an environment variable NOTIFY_SOCKET, which contains a path to an AF_UNIX socket.
    (If the first path byte is @, this means an "abstract" socket, and you should change the 1st byte to 0x00 before using.)
  3. The protocol consists of sending datagrams containing textual (UTF-8) status messages.
    Each message contains newline-separated KEY=value parameters.
  4. When the daemon is ready, it must send READY=1, and systemd will transition the service from "starting" to "running".
