- <listitem><para>Unset the specified control group attributes
- of the specified unit. Takes a unit name and one or more
- attribut names such as <literal>cpu.shares</literal>. This
- operation might or might not have an immediate effect on the
- current kernel attribute value. This will remove any
- persistently stored configuration values for this attribute
- (as set with <command>set-cgroup-attr</command> before),
- unless <option>--runtime</option> is passed, in which case the
- configuration is reset only until the next reboot. Again,
- high-level control group attributes may be used instead of the
- low-level kernel ones. For attributes which take multiple
- values, all currently set values are reset.</para>

- <listitem><para>Add or remove a unit to/from a specific
- control group hierarchy and/or control group path. Takes a
- unit name, plus a control group specification in the syntax
- <replaceable>CONTROLLER</replaceable>:<replaceable>PATH</replaceable>
- or <replaceable>CONTROLLER</replaceable>. In the latter syntax
- (where the path is omitted) the default unit control group
- path is implied. Examples: <literal>cpu</literal> or
- <literal>cpu:/foo/bar</literal>. If a unit is removed from a
- control group hierarchy all its processes will be moved to the
- root group of the hierarchy and all control group attributes
- will be reset. These operations are immediately reflected in
- the kernel hierarchy, and stored persistently to disk (unless
- <option>--runtime</option> is passed).</para>
+ <para>Note that this command allows changing multiple

+ setting them individually. Like unit file configuration
+ settings, assigning the empty list to list parameters will
+ reset the list.</para>
