You'll 1.52 +be able to customize your new system or create your own autonomous 1.53 +distro running in system memory (RAM) that's fully installable on 1.54 +a hard drive or USB key. Once started you'll be able to remove the 1.55 +CD-ROM and still have SliTaz working. SliTaz can also be used as an 1.56 +environment in which we can chroot or use the cdrom for multitasking. 1.57 +The only prerequisite is a host distribution in which you can store 1.58 +libraries, use a compiler and development tools, etc. The host 1.59 +system can be a chrooted development environment, a minimal 1.60 +distro, SliTaz installed on a hard drive or a 'general' distro such 1.61 +as Debian, Slackware, Fedora, Gentoo, Mandriva, Arch, etc. Note 1.62 +that nothing is installed in the host system by our commands. 1.63 +</p> 1.64 +<p> 1.65 +SliTaz uses the 'Swiss Army Knife' BusyBox as the basis of the system and 1.66 +the Linux Kernel, it runs embedded using a small memory footprint and 1.67 +provides many files. BusyBox is our main source of information 1.68 +and it's a utility of the Debian project which we use and cherish. 1.69 +</p> 1.70 +<p> 1.71 +SliTaz uses the Syslinux bootloader and an archived initramfs 1.72 +compressed with cpio. This archive is them decompressed in memory 1.73 +at boot by the kernel into a system of no fixed size, retaining 1.74 +control over init. At the time of compilation or copying of 1.75 +applications, we use strip to clean the repositoiries. The system commands 1.76 +genisoimage or mkisofs are used to create the iso images. To 1.77 +finish, you can test the iso image with Qemu or engrave the 1.78 +generated iso on to a rewritable cdrom. 1.79 +</p> 1.80 +<a name="org"></a> 1.81 +<h3><font color="#6c0023">Organize a working directory</font></h3> 1.82 +<p> 1.83 +To create SliTaz, we need a working directory and several subdirectories 1.84 +Whether you have a chrooted environment for developing or a host 1.85 +system, we advise to use a directory named distro/ in which to 1.86 +work. The distro/ directory can be a simple folder or a partition, 1.87 +but you are obviously free to put all of this elsewhere. 1.88 +</p> 1.89 +<h4>distro/</h4> 1.90 +<p>Contents of a working directory: 1.91 +</p> 1.92 +<ul> 1.93 + <li>rootfs/ --> The root filesystem - this is the root system, designed 1.94 + to operate in RAM, it is used to generate the initramfs image.</li> 1.95 + <li>rootfs.gz --> The initramfs image of our system - a cpio 1.96 + archive compressed with gzip.</li> 1.97 + <li>rootcd/ --> The rootcd. This is the root of the cdrom files.</li> 1.98 + <li>src/ --> The sources, Kernel, Syslinux, Busybox, Dropbear, 1.99 + etc (it can also be a symbolic link).</li> 1.100 +</ul> 1.101 +<p> 1.102 +Thereafter, the initramfs and bootable ISO image (slitaz-cooking.iso) 1.103 +will be created in the root directory of our work named SliTaz/. 1.104 +</p> 1.105 +<h4>Option: rootfs.ext2 - using a virtual hard drive</h4> 1.106 +<p> 1.107 +Option: rootfs.ext2 (root filesystem in ext2) is a virtual hard disk 1.108 +formatted with ext2 and mounted on a (rootfs) loop. A device loop allows 1.109 +a file to be used as a standard device (hard drive, floppy, etc) to build 1.110 +a filesystem inside. This file can be any number of megabytes, we propose 1.111 +20,480, which corresponds to 20MB: 1.112 +</p> 1.113 +<pre> # dd if=/dev/zero of=rootfs.ext2 bs=1k count=20480 1.114 +</pre> 1.115 +<p> 1.116 +Create a ext2 filesystem named rootfs.ext2, the option -F formats the 1.117 +file. Note that the -m 0 option doesn't allocate any space for the user 1.118 +root - by default it occupies approximately 5% and the -t option defines 1.119 +the type of filesystem to be used, such as ext2 or ext3: 1.120 +</p> 1.121 +<pre> # mkfs -t ext2 -F -m 0 rootfs.ext2 1.122 +</pre> 1.123 +<p> 1.124 +We can now assemble rootfs.ext2 with a loop, thanks to the -o loop option 1.125 +provided by the mount utility in the rootfs/ directory. You can check if 1.126 +the assembly went well with the <code>df-h</code> command: 1.127 +</p> 1.128 +<pre> # mkdir rootfs 1.129 + # mount -o loop rootfs.ext2 rootfs 1.130 + # df -h 1.131 +</pre> 1.132 +<p> 1.133 +At the end of the session, you can dismount the volume with umount: 1.134 +</p> 1.135 +<pre> # umount rootfs 1.136 +</pre> 1.137 +<p> 1.138 +Now we can proceed to the construction of the <a href="base-system.html">base SliTaz system</a>. 1.139 +</p> 1.140 + 1.141 +<!-- End of content --> 1.142 +</div> 1.143 + 1.144 +<!-- Footer. --> 1.145 +<div id="footer"> 1.146 + <div class="footer-right"></div> 1.147 + <a href="#top">Top of the page</a> | 1.148 + <a href="index.html">Table of contents</a> 1.149 +</div> 1.150 + 1.151 +<div id="copy"> 1.152 + Copyright © 2008 <a href="http://www.slitaz.org/en/">SliTaz</a> - 1.153 + <a href="http://www.gnu.org/licenses/gpl.html">GNU General Public License</a>;<br /> 1.154 + Documentation is under 1.155 + <a href="http://www.gnu.org/copyleft/fdl.html">GNU Free Documentation License</a> 1.156 + and code is <a href="http://validator.w3.org/">valid xHTML 1.0</a>. 1.157 +</div> 1.158 + 1.159 +</body> 1.160 +</html>
