Description: A target unit is a special type of unit in systemd that groups other units. In the context of systemd, which is a system and service manager for Linux-based operating systems, target units allow for the organization and management of the startup of multiple services and resources in a coherent manner. These units are defined in configuration files that specify how and when the units they group should be started or stopped. Target units are particularly useful for establishing dependencies between services, ensuring that certain services only start after others have begun. This is crucial in environments where the startup order of services can affect the stability and functionality of the system. Additionally, target units can be used to create groups of services that can be started or stopped together, facilitating system administration. For example, a target unit can group all services related to networking, allowing them to be started or stopped simultaneously. In summary, target units are a powerful tool in systemd that enables more efficient and organized management of services in a system.
