Name

create-control-group — create another control group

Synopsis

create-control-group {group}

Description

create-control-group is a utility that creates the process control group group with mkdir(3).

On platforms where /proc/self/cgroup does not exist, this command is a no-op, for script compatibility. Otherwise, that file is searched for a control group record with a blank controller field or (failing that) with a name=systemd controller field.

If a record of the former type is found, version 2 control groups are assumed with the single control group hierarchy rooted at /sys/fs/cgroup. If a record of the latter type is found, version 1 control groups are assumed with the relevant control group hierarchy (the only one that is affected by the command) rooted at /sys/fs/cgroup/systemd.

The command will fail if the process cannot create the given control group and it does not already exist.
