.The following values may be used:" BOOTUP= value , where value is one of the following:" BOOTUP=color means the standard color boot display, where the success or failure ofdevices and services starting up is shown in different colors." BOOTUP=verbose means an old style display, which provides more information thanpurely a message of success or failure." Anything else means a new display, but without ANSI-formatting." RES_COL= value , where value is the number of the column of the screen to startstatus labels.Defaults to 60." MOVE_TO_COL= value , where value moves the cursor to the value in the RES_COLline.Defaults to ANSI sequences output by echo-e." SETCOLOR_SUCCESS= value , where value sets the color to a color indicating suc-cess.Defaults to ANSI sequences output by echo-e, setting the color to green." SETCOLOR_FAILURE= value , where value sets the color to a color indicating failure.Defaults to ANSI sequences output by echo-e, setting the color to red." SETCOLOR_WARNING= value , where value sets the color to a color indicating warn-ing.Defaults to ANSI sequences output by echo-e, setting the color to yellow." SETCOLOR_NORMAL= value , where value sets the color to normal.Defaults to ANSIsequences output by echo-e." LOGLEVEL= value , where value sets the initial console logging level for the kernel.The default is 7; 8 means everything (including debugging); 1 means nothing except kernelpanics.syslogdwill override this once it starts." PROMPT= value , where value is one of the following boolean values:" yes Enables the key check for interactive mode." no Disables the key check for interactive mode.3.3.1.15./etc/sysconfig/ipchainsThe /etc/sysconfig/ipchains file contains information used by the kernel to set upipchainsrules regarding packet filtering.This file is modified by running the service ipchains save command when validipchains rules are in place.You should not manually edit this file.Instead, use theipchains command to configure the necessary packet filtering rules and then save therules to this file. Chapter 3.Boot Process, Init, and Shutdown 693.3.1.16./etc/sysconfig/iptablesLike /etc/sysconfig/ipchains, the /etc/sysconfig/iptables file stores informationused by the kernel to provide specialized packet filtering services.However, this file is usedbyiptablesrather thanipchains.You should not modify this file by hand unless you are familiar with methods used to con-struct iptables rules.These rules are written to /etc/sysconfig/iptables by the ser-vice iptables save command, which stores the current iptables rules by running the/sbin/iptables-saveprogram.Then, wheniptablesis restarted, such as is the case whenthe system is booted, the /sbin/iptables-restoreprogram reads the file and reinstitutesthe packet filtering rules.3.3.1.17./etc/sysconfig/irdaThe/etc/sysconfig/irdafile controls how infrared devices on your system are configuredat startup.The following values may be used:" IRDA= value , where value is one of the following boolean values:" yes irattach will be run, which periodically checks to see if anything is trying toconnect to the infrared port, such as another notebook computer trying to make a net-work connection.For infrared devices to work on your system, this line must be set toyes." no irattachwill not be run, preventing infrared device communication." DEVICE= value , where value is the device (usually a serial port) that handles in-frared connections." DONGLE= value , where value specifies the type of dongle being used for infraredcommunication.This setting exists for people who use serial dongles rather than real in-frared ports.A dongle is a device that is attached to a traditional serial port to commu-nicate via infrared.This line is commented out by default because notebooks with realinfrared ports are far more common than computers with add-on dongles." DISCOVERY= value , where value is one of the following boolean values:d" yes Startsirattachin discovery mode, meaning it actively checks for other infrareddevices.This needs to be turned on for the machine to be actively looking for an infraredconnection (meaning the peer that does not initiate the connection)." no Does not startirattachin discovery mode.3.3.1.18./etc/sysconfig/keyboardThe /etc/sysconfig/keyboard file controls the behavior of the keyboard.The followingvalues may be used:" KEYBOARDTYPE=sun|pc, which is used on SPARCs only.sun means a Sun keyboard is at-tached on/dev/kbd, andpcmeans a PS/2 keyboard connected to a PS/2 port." KEYTABLE= file , where file is the name of a keytable file. 70 Chapter 3.Boot Process, Init, and ShutdownFor example: KEYTABLE="us".The files that can be used as keytables start in/usr/lib/kbd/keymaps/i386and branch into different keyboard layouts from there, alllabeled file.kmap.gz.The first file found beneath/usr/lib/kbd/keymaps/i386thatmatches theKEYTABLEsetting is used.3.3.1.19./etc/sysconfig/kudzuThe /etc/sysconfig/kuzduallows you to specify a safe probe of your system s hardwarebykudzuat boot time.A safe probe is one that disables serial port probing." SAFE= value , where value is one of the following:" yes kuzdudoes a safe probe." no kuzdudoes a normal probe.3.3.1.20./etc/sysconfig/mouseThe /etc/sysconfig/mouse file is used to specify information about the available mouse.The following values may be used:" FULLNAME= value , where value refers to the full name of the kind of mouse beingused." MOUSETYPE= value , where value is one of the following:" microsoft A Microsoft"! mouse." mouseman A MouseMan"! mouse." mousesystems A Mouse Systems"! mouse." ps/2 A PS/2 mouse." msbm A Microsoft"! bus mouse." logibm A Logitech"! bus mouse." atibm An ATI"! bus mouse." logitech A Logitech"! mouse." mmseries An older MouseMan"! mouse." mmhittab An mmhittab mouse." XEMU3= value , where value is one of the following boolean values:" yes The mouse only has two buttons, but three mouse buttons should be emulated." no The mouse already has three buttons." XMOUSETYPE= value , where value refers to the kind of mouse used when X is run-ning.The options here are the same as theMOUSETYPEsetting in this same file." DEVICE= value , where value is the mouse device.In addition,/dev/mouseis a symbolic link that points to the actual mouse device. Chapter 3.Boot Process, Init, and Shutdown 713.3.1.21./etc/sysconfig/namedThe /etc/sysconfig/named file is used to pass arguments to the named daemon at boottime.The named daemon is a Domain Name System (DNS) server which implements theBerkeley Internet Name Domain (BIND) version 9 distribution.This server maintains a tableof which hostnames are associated with IP addresses on the network.Currently, only the following values may be used:" ROOTDIR=" /some/where ", where /some/where refers to the full directory path ofa configured chroot environment under which named will run.This chroot environmentmust first be configured.Typeinfo chrootfor more information on how to do this." OPTIONS=" value ", where value any option listed in the man page fornamedexcept-t.In place of-t, use theROOTDIRline above instead
