How creating quickly a livecd?
					[january 2006]

Intro
=====
	You need a livecd quickly? You don't want to do a LFS? This howto is
	for you. Sounds great.
	Before starting, be sure to have sudo, cloop-utils, chroot, bzip2 and
	mkisofs.
	Let's go to personnalize a morphix Livecd.

First step
==========

	We gonna download some iso and making our folders.
	
		$ cd ~/
		$ mkdir ibuild
		$ cd ibuild
		$ mkdir -p prebuilt/mainmod
		$ cd prebuilt/mainmod
		$ wget http://sigma.livecd.net/~gandalf/BareX.mod.iso.bz2
		$ bunzip2 BareX.mod.iso.bz2
		$ cd ~/ibuild/prebuilt/base/
		$ mkdir temp
		$ mkdir 0.5-pre5 
		$ sudo mount -o loop MorphixBase-0.5-pre5.iso temp
		$ cp -a temp/* 0.5-pre5/.
		$ sudo umount temp

Second step
===========

	The aim is to prepare your iso. We give all informations about
	network.

		$ mkdir -p ~/ibuild/work/livecd/tmpmnt/
		$ sudo mount -o loop ~/ibuild/prebuilt/mainmod/BareX.mod.iso
		/ibuild/work/livecd/tmpmnt/
		$ sudo mkdir -p ~/ibuild/work/livecd/source/
		$ sudo cp -Rp ~/ibuild/work/livecd/tmpmnt/*
		~/ibuild/work/livecd/source/.
		$ sudo cp -Rp ~/ibuild/work/livecd/tmpmnt/*
		~/ibuild/work/livecd/source/.
		$ sudo cp /etc/resolv.conf
		~/ibuild/work/livecd/source/etc/resolv.conf
		$ sudo cp -r barex-fix ~/ibuild/work/livecd/source/morphix/
		$ sudo cp /etc/hosts ~/ibuild/work/livecd/source/etc/hosts
		$ sudo mount --bind /proc ~/ibuild/work/livecd/source/proc
Third step
==========

	Now, we can chrott our iso and do what we want.

		$ sudo chroot ~/ibuild/work/livecd/source/
		# 
		# cat /etc/apt/soruces.list
			deb ftp://ftp.fr.debian.org/debian/ testing main
			deb http://security.debian.org/ testing/updates main
		# apt-get update
		# apt-get install XXXX
		# exit
	
	Don't forget to clean /tmp, `apt-get clean` and so on.

Last step
=========

	Last step but the longest : create your iso.

		# /usr/bin/mkisofs -R -quiet -allow-leading-dots -V "My FS" \
		 --publisher "coin" -o ~/ibuild/work/livecd/temp.iso \
		 -hide-rr-moved -cache-inodes -no-bak -pad \
		 ~/ibuild/work/livecd/source
		# /usr/bin/create_compressed_fs ~/ibuild/work/livecd/temp.iso \
		 65536 > ~/ibuild/work/livecd/release/mainmod/livecd.mod
		# /usr/bin/mkisofs -quiet -pad -l -r -J -V "short" -b \
		 boot/grub/iso9660_stage1_5 -c base/boot.cat -no-emul-boot \
		 -boot-load-size 4 -boot-info-table -hide -rr -moved -o \
		 ~/ibuild/release/livecd.iso ~/ibuild/work/livecd/release

	Ding. It's hot.


Tips
====

1- Want to install an ica client?

		# apt-get install libxaw6 libmotif3
		# ln -s /usr/X11R6/lib/libXm.so.3 /usr/lib/libXm.so.3
		# wget http://philippe.tuxaco.net/debian/icaclient_9.0-2_i386.deb
		# dpkg -i icaclient_9.0-2_i386.deb
		# /usr/lib/ICAClient/wfcmgr

2 - Want to modify the bootsplashscreen ?
	
		$ mount -o loop ./base.iso /mnt/target
	
	mount the boot.img to a directoy

		$ cp -a /mnt/target/* /tmp/newiso
		$ mount -o loop /tmp/newiso/base/boot.img /tmp/bootimage
		$ cp /tmp/bootimage/miniroot.gz /tmp/
		$ gunzip /tmp/miniroot.gz
		$ mount -o loop /tmp/miniroot /tmp/miniroot-dir

	Now, you can change your bootsplash in /bootsplash
	*Your images must be in 16bit color.*

		$ umount /tmp/miniroot-dir
		$ gizp /tmp/miniroot
		$ mv /tmp/miniroot.gz /tmp/bootimage
		$ umount /tmp/bootimage
		
	
Conclusion
==========

	This tutorial's aim is to create a livecd quickly. You can tunned your
	livecd as you want.
