sd_booted

Test whether the system is running the systemd init system

#include <systemd/sd-daemon.h>

int

sd_booted

void

Description

sd_booted() checks whether the system was booted up using the systemd init system.

Return Value

On failure, this call returns a negative errno-style error code. If the system was booted up with systemd as init system, this call returns a positive return value, zero otherwise.

Notes

Internally, this function checks whether the directory /run/systemd/system/ exists. A simple check like this can also be implemented trivially in shell or any other language.
