<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 resource management.</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>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.
