What is the result of the following entry in the /etc/inittab file?
ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now
You find scripts named K11anacron and S15bind9 in the /etc/rc2.d directory. Which script will run first when the system starts up?
You wish to run the fsck command on a partition named /dev/hda1. What command should you run first?
What is the result of the following command?

Review the contents of the scripts at your particular runlevel. In some ...
