55 | <title>Description</title> | |
56 | ||
57 | <para>A unit configuration file whose name ends in | |
58 | <literal>.target</literal> encodes information about a target unit | |
59 | of systemd, which is used for grouping units and as well-known | |
60 | synchronization points during start-up.</para> | |
61 | ||
62 | <para>This unit type has no specific options. See | |
63 | <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry> | |
64 | for the common options of all unit configuration files. The common | |
65 | configuration items are configured in the generic [Unit] and | |
66 | [Install] sections. A separate [Target] section does not exist, | |
67 | since no target-specific options may be configured.</para> | |
68 | ||
69 | <para>Target units do not offer any additional functionality on | |
70 | top of the generic functionality provided by units. They exist | |
71 | merely to group units via dependencies (useful as boot targets), | |
72 | and to establish standardized names for synchronization points | |
73 | used in dependencies between units. Among other things, target | |
74 | units are a more flexible replacement for SysV runlevels in the | |
75 | classic SysV init system. (And for compatibility reasons special | |
76 | target units such as <filename>runlevel3.target</filename> exist | |
77 | which are used by the SysV runlevel compatibility code in systemd. | |
78 | See | |
79 | <citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>7</manvolnum></citerefentry> | |
80 | for details).</para> | |
81 | ||
82 | <para>Unless <varname>DefaultDependencies=</varname> is set to | |
83 | <option>false</option>, target units will implicitly complement | |
84 | all configured dependencies of type <varname>Wants=</varname>, | |
85 | <varname>Requires=</varname>, | |
86 | <varname>RequiresOverridable=</varname> with dependencies of type | |
87 | <varname>After=</varname> if the units in question also have | |
88 | <varname>DefaultDependencies=true</varname>. | |
