NET 4000 Chapter Notes - Chapter 3.3.5: Symbolic Link, Init, Runlevel
Document Summary
The systemd daemon uses boot targets to set the system state. A boot target represents one of several different modes that the linux system can be configured to run in. Earlier versions of linux that were based on the init daemon used runlevels instead of boot targets to set the system state. The default boot target specifies the state that your system will boot into each time it is turned on. In addition, the system state can be dynamically switched between boot targets while the operating system is running. Each boot target is represented by a file (called a target unit) in /usr/lib/systemd/system: Configures the system to run in single user mode with a text-based user interface. This target sets up a base system and opens a rescue shell for troubleshooting system problems. multi-user. target. Configures the system to run in multi-user mode with a text-based user interface. This target is commonly used as the default mode for server systems. graphical. target.
