This is built on the Linux kernel Control Groups ("cgroups") facility. Previously, the kernel's cgroups API was exposed directly as application API, following the rules of the [[Pax Control Groups|http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups/]] document. However, the kernel cgroup interface is in the process of being reworked into an API that requires a single writer in userspace managing it. With this change the cgroup tree becomes private property of that userspace component and is no longer a shared resource. On systemd systems PID 1 takes this role and hence needs to provide APIs for clients to take benefit of the control groups functionality of the kernel. + |
