Live CD (No Install Option)

Created 5/5/2008 by Christopher Hyde of East Brunswick Public Library

To simply modify the LiveCD, Download the ISO file from here:

LiveCD

Then use an ISO editor to modify the following files as needed:

  • printer.conf(see more information below)
  • edit Resetbrowser(see more information below)
  • Modify user.js for homepage. Modify localstore.rdf for toolbar, etc options.

Keep in mind that if you edit the printer.conf or some other linux system files under windows, they may not work on the LiveCD as windows automatically adds characters to the files which linux doesn't like.

Test and Burn to CD! The system loads fairly quickly, as it is only about 168mb.

Actual Edits

Extract files from ISO(right click extract here in linux) Modify Boot List Open /Slax/boot/slax.cfg Change timeout to 1(boots right away, 0 stops system at menu) Remove slax\base\004 thru 006.lzm files Add Printing Create a folder called /etc/cups under the slax/rootcopy directory. Add a file called printer.conf with the following information, suitable for your print setup, where ebpl2 is the server name and Ref B&W Q is the name of the printer Q.

  1. Printer configuration file for CUPS v1.3.7

Then copy userchrome.css into the opt /firefox/chrome directory. Modify user.js for homepage. Modify localstore.rdf for toolbar, etc options. Create a folder under slax/rootcopy called X11/xinit In this folder, copy the following into a file called “xinitrc”

  1. !/bin/sh
  2. $XConsortium: xinitrc.cpp,v 1.4 91/08/22 11:41:34 rws Exp $

userresources=$HOME/.Xresources usermodmap=$HOME/.Xmodmap sysresources=/etc/X11/xinit/.Xresources sysmodmap=/etc/X11/xinit/.Xmodmap

  1. merge in defaults and keymaps

if [ -f $sysresources ]; then xrdb -merge $sysresources fi

if [ -f $sysmodmap ]; then xmodmap $sysmodmap fi

if [ -f $userresources ]; then xrdb -merge $userresources fi

if [ -f $usermodmap ]; then xmodmap $usermodmap fi

  1. Start the window manager:
  2. startkde
  3. /usr/local/bin/xscreensaver
  4. /root/inactivity

Xconf

  1. this makes sure the power management features DO NOT kick in and turn off the monitor(just in case, for the terminal)!

setterm -blank 0 -powersave off -powerdown 0

  1. this makes sure the power management features DO NOT kick in and turn off the monitor!

xset s off -d :0 s 0 –dpms /usr/bin/setterm -blank 0 -store

  1. this runs firefox, and attempts to have it take up the full screen

/opt/firefox/firefox --maximized

Download the extension resetbrowser, and install it under Firefox 2 on a test computer. Copy the folder {ed52a7ae-35c6-40dc-bb21-8dd56e2e89ea} from the extensions directory on the test computer to /opt/firefox/extensions Modify the file /opt/firefox/extensions/{ed52a7ae-35c6-40dc-bb21-8dd56e2e89ea}/defaults/preferences/autoresetbrowser.js if you wish. The default (300000) is for five minutes, or 60000*5(60000 for each minute you want, 10 minutes would be 6000000) pref("autoResetBrowser.timeout", 300000); Cleanup – Preventing CD from Ejecting Under the root copy folder, create a folder called mnt/live. In this, create a file called “cleanup”. Simply doing this will prevent the system from “shutting down properly”, since by default the cleanup file will not be executable. This will prevent the system from shutting down/ejecting the CD.

Tools

Make ISO within linux (from within Slax/slax directory) (run this from the slax directory) sudo mkisofs -o "fslax.iso" -v -J -R -D -A "CDLABEL" -V "CDLABEL" -no-emul-boot -boot-info-table -boot-load-size 4 -b boot/isolinux/isolinux.bin -c boot/isolinux/isolinux.boot ../. Editing LZM files Unpack: lzm2dir /home/chris/Desktop/Slax/slax/base/002-xorg.lzm /tmp/aaaaxorg Repack: dir2lzm /tmp/aaaaxorg/ 002-xorg.lzm
