Run Levels
- How are the run levels different?
- Different run levels may start different process than
others.
- Each run level has a very specific set of processes
that startup and shutdown in a particular order.
- Where can I see the processes and their ordering?
run level 0
--> /etc/rc.d/rc0.d
run level 1 -->
/etc/rc.d/rc1.d
run level 2
--> /etc/rc.d/rc2.d
run level 3 --> /etc/rc.d/rc3.d
run level 4 --> /etc/rc.d/rc4.d
run level 5 --> /etc/rc.d/rc5.d
run level 6 --> /etc/rc.d/rc6.d
