-                <para>This function is provided by the reference
-                implementation of APIs for new-style daemons and
-                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.</para>

-                <para>Internally, this function checks whether the
-                <filename>/sys/fs/cgroup/systemd</filename> virtual file
-                system is mounted, by comparing the st_dev value of
-                the <function>stat()</function> data of
-                <filename>/sys/fs/cgroup</filename> and
-                <filename>/sys/fs/cgroup/systemd</filename>.</para>
-
-                <para>For details about the algorithm check the
-                liberally licensed reference implementation sources:

-                <para><function>sd_booted()</function> is implemented

-                <filename>sd-daemon.c</filename> and
-                <filename>sd-daemon.h</filename> files. These
-                interfaces are available as shared library, which can
-                be compiled and linked to with the

-                may copy the implementation into their source
