The Linux world has largely transitioned away from the traditional

SysV init system, the /etc/inittab file, and run levels. Most modern distros now use the systemd init system. Discuss three ways in which systemd is superior to SysV. To augment your discussion, provide your terminal output to demonstrate the following:
How can you determine the default systemd target for your system?
How would you list the active services on your Linux system?
How can you determine the status of the firewall service?
How could you troubleshoot the cron process? Hint, use a command to review what systemd knows about the recent history of cron.
How would you analyze the systemd boot process and how would you show the amount of time each process uses at boot?
