systemd.target(5)
NAME
systemd.target - Target unit configuration
SYNOPSIS
target.target
DESCRIPTION
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.
This unit type has no specific options. See systemd.unit(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.
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 systemd.special(7) for details).
AUTOMATIC DEPENDENCIES
Unless DefaultDependencies= is set to no in either of related units or
an explicit ordering dependency is already defined, target units will
implicitly complement all configured dependencies of type Wants= or
Requires= with dependencies of type After=. Note that Wants= or
Requires= must be defined in the target unit itself --- if you for
example define Wants=some.target in some.service, the implicit ordering
will not be added.
All target units automatically gain Conflicts= dependency against
shutdown.target unless DefaultDependencies= is set to no.
