AUTHOR: Sylvie Migneault DATE: 2005-11-07 LICENSE: GNU Free Documentation License Version 1.2 SYNOPSIS: lfscd-remastering-HOWTO DESCRIPTION: This is a guide that will show you how to remaster LFSliveCD-x86-6.1-3 Note: commands should appear on one line, after the symbol # PREREQUISITES: - at least 1 GB of FREE RAM+Swap total (e.g. 256M ram, and 750M swap AVAILABLE) - 2 GB free on a Linux filesystem formatted disk partition - Host System with SquashFS supported - mksquashfs tools - mkisofs tools - link: http://squashfs.sourceforge.net HINT: Contents -------- 1. Host System Requirements 2. LiveCD's structure 3. My working environment 4. Boot from the lfslivecd-x86-6.1-3 and mount it 5. Mount the work partition, create directories 6. Uncompress .root.sqfs 7. Copy CD's contents into lfscd (not .root.sqfs) 8. Install mksquashfs 9. chroot into lfshd 10. Install any programs 11. Create .root.sqfs 12. Create iso file 13. Burn and test 1. Host System Requirements ------------------------ I use lfslivecd-x86-6.1-3 because SquashFS is supported by the kernel. If you want to use your Linux system, patch your kernel with SquashFS. 2. LiveCD's structure ------------------ /boot /sources .root.sqfs I work with ".root.sqfs" file 3. My working environment ---------------------- /dev/hdc my CD drive /mnt/cdrom content of lfslivecd-x86-0.6-3 /mnt/hda5 my working partition /mnt/hda5/lfscd content of final CD /mnt/hda5/lfshd chroot environment /mnt/hda5/lfsiso content of ISO files /mnt/hda5/lfstmp tempory directory 4. Boot from the lfslivecd-x86-6.1-3 and mount it ---------------------------------------------- # mkdir /mnt/cdrom # mount /dev/hdc /mnt/cdrom 5. Mount the work partition, create directories -------------------------------------------- # mkdir /mnt/hda5 # mount /dev/hda5 /mnt/hda5 # cd /mnt/hda5 # mkdir lfscd lfshd lfstmp lfsiso 6. Uncompress .root.sqfs --------------------- # cd /mnt/cdrom # mount .root.sqfs /mnt/hda5/lfstmp -o loop # cd /mnt/hda5/lfstmp # cp -Rp * /mnt/hda5/lfshd # cd .. # umount lfstmp/ 7. Copy LiveCD's content into lfscd (not .root.sqfs) ------------------------------------------------- # cd /mnt/cdrom # cp -Rp * /mnt/hda5/lfscd # cd .. # umount cdrom/ 8. Install mksquashfs ------------------ Before starting, i have downloaded squashfsXX.tar.gz at this URL http://squashfs.sourceforge.net copy it into /sources If squashfsXX.tar.gz is on floppy Insert floppy in the floppy drive # mkdir /mnt/floppy # mount /dev/fd0 /mnt/floppy # cd /mnt/floppy # cp squashfsXX.tar.gs /sources # cd .. # umount floppy/ # cd /sources # tar -xvf squashfsXX.tar.gz # cd squashfsXX # cd squashfs-tools # make install mksquashfs into host system # cp mksquashfs /usr/sbin install mksquashfs into chroot environment # cp mksquashfs /mnt/hda5/lfshd/usr/sbin 9. chroot into lfshd ----------------- create the environment variable TOTO, verify the output # export TOTO=/mnt/hda5/lfshd # echo $TOTO Make sure the output shows is: /mnt/hda5/lfshd run the following command: # chroot "$TOTO" /usr/bin/env -i \ HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \ PATH=/bin:/usr/bin:/sbin:/usr/sbin \ /bin/bash --login +h reference: http://www.linuxfromscratch.org/lfs/view/stable/chapter06/chroot.html 10. Install any programs -------------------- - ./configure - make - make install - ... - for exit the chroot environment: # exit 11. Create .root.sqfs ----------------- # cd /mnt/hda5 # mksquashfs lfshd/ /mnt/hda5/lfscd/.root.sqfs 12. Create iso file --------------- mkisofs tool is not present on lfslivecd-x86-6.1-3. umount all: # cd / # umount /mnt/hda5 Reboot your PC unless lfslivecd. Create ISO file with this command: # mkisofs -pad -l -r -J -v -V "LFS_CD" -no-emul-boot -boot-load-size 4 -boot-info-table \ -b boot/isolinux/isolinux.bin -c boot/boot.cat -hide-rr-moved \ -o /mnt/hda5/lfsiso/livecd-remaster.iso /mnt/hda5/lfscd 13. Burn and test ------------- «Have a fun!» ;-) ACKNOWLEDGEMENTS: The team of «Linux from scratch» and all users.
