NAME
cgmanager - a daemon to manage cgroups
SYNOPSIS
cgmanager [OPTION]...
DESCRIPTION
cgmanager is a daemon to manage cgroups. Programs and users can make D-Bus requests to
administer cgroups over which they have privilege. To ensure that users may not exceed
their privilege in manipulating cgroups, the cgroup manager accepts regular D-Bus requests
only from tasks within its own process-id and user namespaces. For tasks in private
namespaces (such as containers), SCM-enhanced D-Bus calls are available. Using these man‐
ually is not recommended. Rather, each container is advised to run a cgproxy, which will
forward plain D-Bus requests as SCM-enhanced D-Bus requests to the host cgmanager.
