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, target units will implicitly complement all configured
       dependencies of type Wants=, Requires= with dependencies of type After=, unless an ordering dependency of
       any kind between the target and the respective other unit is already in place. Note that this behaviour
       is disabled if either unit has DefaultDependencies=no.
