The systemd service and setting runlevels

The systemd service doesn't use runlevels as SysV or Upstart do. The alternatives for systemd are called targets. Their purpose is to group a set of systemd units (not only services, but also sockets, devices, and so on) through a chain of dependencies.

How to do it…

Managing targets with systemd is pretty simple, as shown through the following steps:

1. List all target units, as follows:

   ~]# systemctl list-unit-files --type target
   UNIT FILE                 STATE   
   anaconda.target           static  
   basic.target              static  
   bluetooth.target          static  
   cryptsetup.target         static  
   ctrl-alt-del.target       disabled
   default.target            enabled
   ...
   
   sysinit.target            static  
   system-update.target      static  
   time-sync.target          static  
   timers.target             static  
   umount.target             static  
   
   58 unit files listed.
   ~]#
