  23 systemd.target \- Target unit configuration
  24 .SH "SYNOPSIS"
  25 .PP
  26 \fItarget\fR\&.target
  27 .SH "DESCRIPTION"
  28 .PP
  29 A unit configuration file whose name ends in
  30 "\&.target"
  31 encodes information about a target unit of systemd, which is used for grouping units and as well\-known synchronization points during start\-up\&.
  32 .PP
  33 This unit type has no specific options\&. See
  34 \fBsystemd.unit\fR(5)
  35 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\&.
  36 .PP
  37 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
  38 runlevel3\&.target
  39 exist which are used by the SysV runlevel compatibility code in systemd\&. See
  40 \fBsystemd.special\fR(7)
  41 for details)\&.
  42 .PP
  43 Unless
  44 \fIDefaultDependencies=\fR
  45 is set to
  46 \fBfalse\fR, target units will implicitly complement all configured dependencies of type
  47 \fIWants=\fR,
  48 \fIRequires=\fR,
  49 \fIRequiresOverridable=\fR
  50 with dependencies of type
  51 \fIAfter=\fR
  52 if the units in question also have
  53 \fIDefaultDependencies=true\fR\&.
