This script itself launches some other smaller 1.56 +scripts which deal with the internationalization or the 1.57 +commands placed for the system to start. 1.58 +</p> 1.59 + 1.60 +<a name="init.d"></a> 1.61 +<h3><font color="#6c0023">/etc/init.d/* - Directory of scripts and daemons</font></h3> 1.62 +<p> 1.63 +The directory /etc/init.d contains all of the rc scripts, 1.64 +scripts finishing with '.sh' are simple shell scripts and 1.65 +daemons such as 'dropbear' or 'lighttpd' are scripts 1.66 +that launch a service. The daemon scripts can start, stop or 1.67 +restart through the command: 1.68 +</p> 1.69 +<pre> # /etc/init.d/daemon [start|stop|restart] 1.70 +</pre> 1.71 +<p> 1.72 +On SliTaz you will find a /etc/init.d/README describing the 1.73 +basic function of rc scripts. Also note that all startup 1.74 +scripts and daemons can call upon the <code>/etc/init.d/rc.functions</code> 1.75 +file. This file makes it possible to include various functions 1.76 +in rc scripts. SliTaz uses a function <code>status</code> to check whether 1.77 +the previous command has succeeded (0) or not. 1.78 +</p> 1.79 + 1.80 +<a name="rcS"></a> 1.81 +<h3><font color="#6c0023">/etc/init.d/rcS - Primary initialization script</font></h3> 1.82 +<p> 1.83 +The <code>/etc/init.d/rcS</code> script configures all the 1.84 +basic services and initializes the base system. It begins by 1.85 +mounting the filesystems and starts services like syslogd, klogd, 1.86 +mdev and cleans up the system and so on. It 1.87 +uses the configuration file <code>/etc/rcS.conf</code> to locate which daemons 1.88 +and scripts to launch at startup. You can browse the script 1.89 +to know which commands are executed: 1.90 +</p> 1.91 +<pre> # nano rootfs/etc/init.d/rcS 1.92 +</pre> 1.93 + 1.94 + 1.95 +<a name="rc-scripts"></a> 1.96 +<h3><font color="#6c0023">Specific scripts and daemons</font></h3> 1.97 + 1.98 +<h4>bootopts.sh - LiveCD mode options</h4> 1.99 +<p> 1.100 +This script is used to configure the LiveCD options passed 1.101 +at boot time and is readable via the /proc/cmdline file. 1.102 +This is the script that allows you to use a USB key or 1.103 +external hard disk <code>/home</code> partition with the option home=usb 1.104 +or home=sda[1-9] or directly specify the language and 1.105 +keyboard parameters. 1.106 +</p> 1.107 + 1.108 +<h4>network.sh - Initializing the network</h4> 1.109 +<p> 1.110 +This script searches the network.sh configuration file 1.111 +/etc/network.conf for the network interface to use; if one wants to 1.112 +launch the DHCP client (or not) or if you want to use a fixed 1.113 +(static) IP. On SliTaz the /etc/init.d/network.sh 1.114 +script configures the network interfaces to start using the 1.115 +information contained in /etc/network.conf. If the variable 1.116 +$DHCP is equal to yes, then the /etc/init.d/network.sh 1.117 +script launches the DHCP client on the $INTERFACE interface. 1.118 +</p> 1.119 + 1.120 +<h4>i18n.sh - Internationalization</h4> 1.121 +<p> 1.122 +SliTaz backs up the configuration of the default locale in 1.123 +/etc/locale.conf which is read by /etc/profile at each 1.124 +login. The /etc/locale.conf is generated during boot time 1.125 +thanks to the /etc/i18n.sh script. This script launches the 1.126 +'tazlocale' application if /etc/locale.conf doesn't exist. 1.127 +We use the same process for the keyboard layout using 'tazkmap' 1.128 +and the /etc/kmap.conf configuration file. Both applications 1.129 +are installed and located in /sbin and use dialog and the 1.130 +ncurses library. The script also checks whether the 1.131 +configuration file for the time zone /etc/TZ exists, 1.132 +otherwise it creates one relying on the keyboard configuration. 1.133 +</p> 1.134 + 1.135 +<h4>local.sh - Local commands</h4> 1.136 +<p> 1.137 +The /etc/init.d/local.sh script allows the system administrator 1.138 +to add local commands to be executed at boot. Example: 1.139 +</p> 1.140 +<pre class="script">#!/bin/sh 1.141 +# /etc/init.d/local.sh: Local startup commands. 1.142 +# All commands here will be executed at boot time. 1.143 +# 1.144 +. /etc/init.d/rc.functions 1.145 + 1.146 +echo "Starting local startup commands... " 1.147 + 1.148 +</pre> 1.149 + 1.150 +<h4>rc.shutdown</h4> 1.151 +<p> 1.152 +This script is invoked by /etc/inittab during system shutdown. 1.153 +It also stops all daemons via the variable RUN_DAEMONS in 1.154 +the primary <code>/etc/rcS.conf</code> configuration file. 1.155 +</p> 1.156 + 1.157 +<a name="inittab"></a> 1.158 +<h3><font color="#6c0023">/etc/inittab - Configuration file init</font></h3> 1.159 +<p> 1.160 +The first file read by the Kernel at boot. It defines the 1.161 +initialization script (/etc/init.d/rcS), shells (ttys) and 1.162 +actions in the event of a reboot or disruption.
