.SH "NAME"
systemd.target \- Target unit configuration
.SH "SYNOPSIS"
.PP
\fItarget\fR\&.target
.SH "DESCRIPTION"
.PP
A unit configuration file whose name ends in
"\&.target"
encodes information about a target unit of systemd, which is used for grouping units and as well\-known synchronization points during start\-up\&.
.PP
This unit type has no specific options\&. See
\fBsystemd.unit\fR(5)
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\&.
.PP
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
runlevel3\&.target
exist which are used by the SysV runlevel compatibility code in systemd\&. See
\fBsystemd.special\fR(7)
for details)\&.
.PP
Unless
\fIDefaultDependencies=\fR
is set to
\fBfalse\fR, target units will implicitly complement all configured dependencies of type
\fIWants=\fR,
\fIRequires=\fR,
\fIRequiresOverridable=\fR
with dependencies of type
\fIAfter=\fR
if the units in question also have
\fIDefaultDependencies=true\fR\&.
