What are systemd targets?
Target units are used for grouping and ordering other units. systemd manages starting several related process at the same time with the help of target units. Some targets, such as multi-user.target, define a specific state of the system and can be considered as more robust and flexible equivalents of SysV runlevels. At the same time, other targets do not offer any additional functionality except grouping units to manage dependencies effectively. The target unit configuration files are stored in the /usr/lib/systemd/system directory.
The following table lists important targets, along with their equivalent runlevels and their descriptions:
