<title>Description</title>
|
|
|
|
<para>A unit configuration file whose name ends in
|
|
<literal>.target</literal> encodes information about a target unit
|
|
of systemd, which is used for grouping units and as well-known
|
|
synchronization points during start-up.</para>
|
|
|
|
<para>This unit type has no specific options. See
|
|
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
|
for the common options of all unit configuration files. The common
|
|
configuration items are configured in the generic [Unit] and
|
|
[Install] sections. A separate [Target] section does not exist,
|
|
since no target-specific options may be configured.</para>
|
|
|
|
<para>Target units do not offer any additional functionality on
|
|
top of the generic functionality provided by units. They exist
|
|
merely to group units via dependencies (useful as boot targets),
|
|
and to establish standardized names for synchronization points
|
|
used in dependencies between units. Among other things, target
|
|
units are a more flexible replacement for SysV runlevels in the
|
|
classic SysV init system. (And for compatibility reasons special
|
|
target units such as <filename>runlevel3.target</filename> exist
|
|
which are used by the SysV runlevel compatibility code in systemd.
|
|
See
|
|
<citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>7</manvolnum></citerefentry>
|
|
for details).</para>
|
|
|
|
<para>Unless <varname>DefaultDependencies=</varname> is set to
|
|
<option>false</option>, target units will implicitly complement
|
|
all configured dependencies of type <varname>Wants=</varname>,
|
|
<varname>Requires=</varname>,
|
|
<varname>RequiresOverridable=</varname> with dependencies of type
|
|
<varname>After=</varname> if the units in question also have
|
|
<varname>DefaultDependencies=true</varname>.
