[SOLVED] Entries in /etc/inittab

I have been using /etc/inittab in my Linux systems for a while now. Although I am noticing that Mageia does not have this feature?? (true or not).
If there is no /etc/inittab configuration, what will start up the applications and insure that they remain running?
Is this the systemd utility? (sorry about answering my own questions here, but I want to fully understand the methods employed).
Thank you.
