<para>Processes systemd spawns are placed in individual Linux
control groups named after the unit which they belong to in the
private systemd hierarchy. (see <ulink

+ url="https://www.kernel.org/doc/Documentation/cgroup-v1/cgroups.txt">cgroups.txt</ulink>
for more information about control groups, or short "cgroups").
systemd uses this to effectively keep track of processes. Control
group information is maintained in the kernel, and is accessible
