When configuring a systemd service unit file, which Type setting will only consider the service started after the process finishes initializing and explicitly signals that it is ready to accept connections or tasks?
Type=notify is used for daemons that call sd_notify() to send a READY=1 message to the systemd notification socket. Systemd will not mark the service active, nor start units that depend on it, until this message is received. Type=simple is considered active immediately after the main process is forked (or execed in the case of Type=exec). Type=forking assumes the service is ready once the parent process exits. Type=dbus waits until the specified D-Bus name is acquired. Only notify relies on an explicit ready signal from the service itself.
