This is a recurring submission and includes corrections to various issue spotted. I guess I can just skip over reporting ubiquitous comma placement fixes…

<title>Description</title>
|
|
|
|
<para>Scope units are not configured via unit configuration files,
|
|
but are only created programmatically using the bus interfaces of
|
|
systemd. They are named similar to filenames. A unit whose name
|
|
ends in <literal>.scope</literal> refers to a scope unit. Scopes
|
|
units manage a set of system processes. Unlike service units, scope
|
|
units manage externally created processes, and do not fork off
|
|
processes on its own.</para>
|
|
|
|
<para>The main purpose of scope units is grouping worker processes
|
|
of a system service for organization and for managing resources.</para>
|
|
|
|
<para><command>systemd-run <option>--scope</option></command> may
|
|
be used to easily launch a command in a new scope unit from the
|
|
command line.</para>
|
|
|
|
<para>See the <ulink
|
|
url="http://www.freedesktop.org/wiki/Software/systemd/ControlGroupInterface/">New
|
|
Control Group Interfaces</ulink> for an introduction on how to make
|
|
use of scope units from programs.</para>
|
|
|
|
<para>Unless <varname>DefaultDependencies=false</varname>
|
|
is used, scope units will implicitly have dependencies of
|
|
type <varname>Conflicts=</varname> and
|
|
<varname>Before=</varname> on
|
|
<filename>shutdown.target</filename>. These ensure
|
|
that scope units are removed prior to system
|
|
shutdown. Only scope units involved with early boot or
|
|
late system shutdown should disable this option.
