Notes
- This function is provided by the reference

- distributed with the systemd package. The algorithm it
- implements is simple, and can easily be reimplemented
- in daemons if it is important to support this
- interface without using the reference
- implementation.

Internally, this function checks whether the
- /cgroup/systemd virtual file
- system is mounted, by comparing the st_dev value of
- the stat() data of
- /cgroup and
- /cgroup/systemd.
