<title>Description</title>
<para>A unit configuration file whose name ends in
<filename>.target</filename> 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
seperate [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 in
fact for compatibility reasons there exist special
target units such as
<filename>runlevel3.target</filename> that are used by
the SysV runlevel compatibility code in systemd. See
<citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>7</manvolnum></citerefentry>
for details).</para>
