about systemd: how to change default runlevel (previously using inittab)

systemd does not use /etc/inittab file to change the default runlevel. systemd uses symlinks to point to the default runlevel. You have to delete the existing symlink first before creating a new one. # rm /etc/systemd/system/default.target example to switch to runlevel 3 : # ln -sf /lib/systemd/system/multi-user.target /etc/systemd/system/default.target next example if you want to switch to run level 5 : # ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target another options that may apply : poweroff.target --> runlevel 0 rescue.target    --> runlevel 1 multi.user.target --> runlevel 2,3,4 graphical.target --> runlevel 5 reboot.target --> runlevel 6 source: http://fedoraproject.org/wiki/Systemd
