Tiny SliTaz goals

+ Useful software, expansible, easy to configure, runs fully in RAM, + simple, light and fast for minimum hardware resources: ie fits on + one floppy disk (IDE disk optional), runs on a 386sx processor and + needs as little memory as possible (currently 8 MB with a 2.6.34 + kernel). + + Example +

+ +

Why this builder ?

+ Tiny SliTaz should be as small as possible. Only the necessary + software is kept. The package manager is run using this website. +

+ +

How is it built ?

+ Tiny SliTaz uses a Linux kernel + with an + embedded filesystem. An extra initramfs can also be loaded with + the configuration and extra packages. +

+ The initramfs is based on uClibc and + busybox with its config + files and the packages + + slitaz-base-files and + + slitaz-boot-scripts. +

+The file /etc/packages.conf in the initramfs holds all information +to rebuild your Tiny SliTaz system. You should upload your +/etc/packages.conf first if you want to upgrade your system only. +

+ + + + +

+You can upload a tazpkg file (.tazpkg) or a tarball of tazpkg files (.tar). +These packages will extend the official packages list and will be chosen when +the package names are found to be matching. You can find some examples in the +Tiny SliTaz repository. +

+ +

+ + +

Linux kernel

+You can upload a custom kernel or use an official one. +Your kernel should have an embedded initramfs with busybox like +this one. +

+ + + +

Going further

+Tiny SliTaz should be smaller to have more functionality +and/or needs less RAM.
+The kernel can be tuned/patched +or you can use an earlier version. +

+You can test Tiny SliTaz without pre-historic hardware using qemu: +

+qemu -cpu 486 -m 8 -net nic,model=ne2k_isa -net tap -fda slitaz.img
+

+Or +

+qemu -cpu 486 -m 8 -net nic,model=ne2k_isa -net tap -snapshot \
+     -kernel kernel -initrd rootfs.gz /dev/zero
+

+And the executable file /etc/qemu-ifup: +

+#!/bin/sh
+
+if [ -x /usr/sbin/openvpn ]; then
+	openvpn --mktun --dev $1 --user `id -un`
+else
+	tunctl -u `id -un` -t $1                           
+fi                              
+ifconfig $1 192.168.0.1 broadcast 192.168.0.255 netmask 255.255.255.0
+

+You can also update the file /etc/resolv.conf on the Tiny SliTaz guest with your +nameserver(s) and enable the ip routing on your desktop: +

+# echo 1 > /proc/sys/net/ipv4/ip_forward
+# yes y | tazpkg get-install iptables
+# iptables -t nat -A POSTROUTING -j MASQUERADE
