                     87: When you boot your computer system (by turning on the power,
                     88: by hitting the reset switch, or by typing <Ctrl><Alt><Del>),

                     97: using /etc/fsck.  If the filesystems check without errors,
                     98: the system goes into multi-user mode, automatically executing
                     99: the commands in the file /etc/rc.  You can interrupt file system
                    100: checking by typing <Ctrl-C>.
