 * mount in a loop the iso;

 * copy the content of the image in a directory, except for the main squashfs filesystem (on ubuntu and debian: filesystem.squash; on dynebolic: dyne.sys);
 * unsquash the squashfs image file into another directory;
 * Add resolv.conf and hosts in /etc by hand or copying from your system;
 * mount the dev,proc and sys filesystems into the uncompressed directory;
 * do some minor stuff for having the system ready for your tweaks.

=== Requirements ===

You need the squashfs-tools.

{{{
apt-get install squashfs-tools
}}}

=== HOWTO ===

{{{

# we choose pd/ as our working directory, so...

mkdir pd
cd pd

sudo mount puredyne.iso /mnt -o loop
mkdir extract-cd
rsync --exclude=/live/filesystem.squashfs -a /mnt/ extract-cd
# for d:b: rsync --exclude=/dyne/dyne.sys -a /mnt extract-cd/

sudo unsquashfs /mnt/live/filesystem.squashfs
# for d:b: sudo unsquashfs /mnt/dyne/dyne.sys

sudo mv squashfs-root edit

# use resolv.conf and hosts from your system, or edit them by hand...
sudo cp /etc/resolv.conf edit/etc/
sudo cp /etc/hosts edit/etc/

# if you are into your pd/ directory with the system extracted as above,
# just cut'n paste from here to start working on the system.

sudo mount --bind /dev/ edit/dev
sudo chroot edit

mount -t proc none /proc
mount -t sysfs none /sys
mount -t devpts none /dev/pts

# To avoid locale problems during installation of new packages, you need to export 2 system variables:

export HOME=/root
export LC_ALL=C

# You also need to do this as root (that's for some reasons connected with a couple of dbus bugs).
# If you are re-chrooting to a system you're working on, don't mind about warnings or errors.

dbus-uuidgen > /var/lib/dbus/machine-id
dpkg-divert --local --rename --add /sbin/initctl
ln -s /bin/true /sbin/initctl

#done!
}}}

That's all folks! ;)

=== Suggestions ===

When you want to remove packages remember to use purge
I investigated a bit the matter, not enough to know whats going on but enough to know is a good practice.

Once in the chroot start poking:

{{{

# refresh your list
apt-get update

# some must have
apt-get install htop modconf

# some multimedia
apt-get install cinelerra sox twolame mpeg2dec a52dec libsox-fmt-all a52dec darkice darksnow

}}}

=== rsync to carry the pack for working out of home ===

{{{
rsync --exclude=/edit/dev --exclude=/edit/proc --exclude=/edit/sys -auvz /home/youruser/wherever/src/pd/ /media/usbdisk/pd/
}}}

In this way you rsync your pd/ working directory on a same pd/ dir on your usb key, so you can work everywhere on your eeepc. ;)

=== Closing ===

{{{

aptitude clean
rm -rf /tmp/* ~/.bash_history
rm /etc/resolv.conf
rm /var/lib/dbus/machine-id
rm /sbin/initctl
dpkg-divert --rename --remove /sbin/initctl
dpkg -l > packages.txt
umount /proc
umount /sys
umount /dev/pts
exit
sudo umount edit/dev
sudo mv edit/packages.txt extract-cd/live/

=== Creating the ISO ===

==== Regenerate the manifest ====

Into the pd dir:

{{{
# creiamo il file
sudo touch extract-cd/live/filesystem.manifest
sudo chmod a+w extract-cd/live/filesystem.manifest
#
sudo chroot edit dpkg-query -W --showformat='${Package} ${Version}\n' > extract-cd/live/filesystem.manifest

#
}}}

==== Compress the filesystem ====

{{{
# cancelliamo il vecchio squashfs eventualmente in mezzo alle palle
sudo rm extract-cd/live/filesystem.squashfs

# creiamo il nuovo squashfs. La pagina Debian live parla di una opzione -nolzma da mettere
# alla fine, che pero' NON ESISTE:
#
# https://help.ubuntu.com/community/LiveCDCustomization
#
# Note: The -nolzma option is only available from Hardy , and was removed in Karmic.
# Also, the squashfs has to be generated using a version of mksquashfs that is compatible
# with the kernel used on the CD you are customizing. For example, you cannot generate
# a jaunty squashfs on karmic, as the jaunty kernel is not able to mount a squashfs
# prepared using mksquashfs from karmic. O_o

sudo mksquashfs edit extract-cd/live/filesystem.squashfs

#
}}}

==== Set an image name in extract-cd/README.diskdefines ====

maybe is unuseful?

{{{

sudo joe extract-cd/README.diskdefines

}}}

(you can use "sudo vim extract-cd/README.diskdefines" if you have difficulties understanding joe. AHHAHAHAH)

==== MD5sum ====

Remove old md5sum.txt and calculate new md5 sums

{{{

cd extract-cd
sudo rm md5sum.txt
find -type f -print0 | sudo xargs -0 md5sum | grep -v isolinux/boot.cat | sudo tee md5sum.txt

}}}

==== CREATE THE ISO IMAGE ====

{{{

Remaster your own live installer, live iso

this came from Ubuntu Live CD Customization


Description

Fetch your favorite iso, in the following examples we will take puredyne-911-carrot_and_coriander iso to show that this procedures can apply to a lot of different isos/systems.

The basic procedure is simple:

  • mount the ISO image in loop mode;
  • copy the content of the image in a directory, except for the main squashfs filesystem (on ubuntu and debian: filesystem.squash; on dynebolic: dyne.sys);
  • unsquash the squashfs image file into another directory;
  • Add resolv.conf and hosts in /etc by hand or copying from your system;
  • mount the dev,proc and sys filesystems into the uncompressed directory;
  • do some minor stuff for having the system ready for your tweaks.

Requirements

You need the squashfs-tools.

apt-get install squashfs-tools

HOWTO

# we choose pd/ as our working directory, so...

mkdir pd
cd pd

sudo mount puredyne.iso /mnt -o loop
mkdir extract-cd
rsync --exclude=/live/filesystem.squashfs -a /mnt/ extract-cd
# for d:b: rsync --exclude=/dyne/dyne.sys -a /mnt extract-cd/

sudo unsquashfs /mnt/live/filesystem.squashfs
# for d:b: sudo unsquashfs /mnt/dyne/dyne.sys 

sudo mv squashfs-root edit

# use resolv.conf and hosts from your system, or edit them by hand...
sudo cp /etc/resolv.conf edit/etc/
sudo cp /etc/hosts edit/etc/

# if you are into your pd/ directory with the system extracted as above, 
# just cut'n paste from here to start working on the system.

sudo mount --bind /dev/ edit/dev
sudo chroot edit

mount -t proc none /proc
mount -t sysfs none /sys
mount -t devpts none /dev/pts
