systemd.target

A .target unit configuration file is used for:

• grouping units via dependencies (useful as boot targets)
• establish standardized names for synchronization points used in dependencies between units during start-up.

Target units do not offer any additional functionality on top of the generic functionality provided by units.

Among other things, target units are a more flexible replacement for SysV runlevels in the classic SysV init system.
