SD_BOOTED(3) sd_booted SD_BOOTED(3)
sd_booted - Test whether the system is running the systemd init
system
#include <systemd/sd-daemon.h>
int sd_booted(void);
sd_booted() checks whether the system was booted up using the systemd
init system.
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.
These APIs are implemented as a shared library, which can be compiled
and linked to with the libsystemd pkg-config(1) file.
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.
