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

Примечание (Note)
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.
