<title>Description</title>
<para>
<command>lxc-cgroup</command> gets or sets the value of a
<replaceable>state-object</replaceable> (e.g., 'cpuset.cpus')
in the container's cgroup for the corresponding subsystem (e.g.,
'cpuset'). If no <optional>value</optional> is specified, the
current value of the <replaceable>state-object</replaceable> is
displayed; otherwise it is set.
</para>
<para>
Note that <command>lxc-cgroup</command> does not check that the
<replaceable>state-object</replaceable> is valid for the running
kernel, or that the corresponding subsystem is contained in any
mounted cgroup hierarchy.
