I know that,
run level=0 => Halt/Shuts down system run level=1 => Single-User Mode run level=2 => Multi-User Mode run level=3 => Multi-User Mode with Networking run level=4 => Undefined run level=5 => level 3 + display managers run level=6 => Reboot
what I am interested to know is,
What is the difference in both the configurations for httpd service? (additional general description is fine)
Is it a good practice to use all run levels for a particular service?
and anything important that one should to know about?
