The "include" files had type "book" for some raeason. I don't think this is meaningful. Let's just use the same everywhere. $ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n "http^gms' man/*.xml

<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>

|
|
Control Group Interfaces</ulink> for an introduction on how to make
|
|
use of scope units from programs.</para>

type <varname>Conflicts=</varname> and

<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

<varname>DefaultDependencies=</varname> option.</para></listitem>
