systemd.target — Target unit configuration
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
which are used by the SysV runlevel compatibility code in systemd.
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
Requires= with dependencies of type
After=. Note that
Requires= must be defined in the target unit itself — if
you for example define
some.service, the implicit ordering will not be added.
All target units automatically gain
dependency against shutdown.target unless
