At the command prompt, type runlevel and press Enter. What is your current runlevel? What is the most recent runlevel? =>N 5 03. At the command prompt, type cat /etc/inittab and press Enter. View the commented sections. Why is /etc/inittab not used in Fedora 20? => # inittab is no longer used. # # ADDING CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM. # # Ctrl-Alt-Delete is handled by /usr/lib/systemd/system/ctrl-alt- del.target # # systemd uses 'targets' instead of runlevels. By default, there are two main targets: # # multi-user.target: analogous to runlevel 3 # graphical.target: analogous to runlevel 5 # # To view current default target, run: # systemctl get-default # # To set a default target, run: # systemctl set-default TARGET.target 04. At the command prompt, type ls /usr/lib/systemd/system and press Enter.
