- What are systemd targets, and how do they relate to old runlevels?
A target is a group of units that represents a system state, such as multi-user.target (text mode, networking) or graphical.target (with a desktop). They replace SysV runlevels: runlevel 3 is multi-user.target and 5 is graphical.target. Check or change with systemctl get-default and set-default.
