=== 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. ;)

Remaster your own live installer, live iso

this came from Ubuntu Live CD Customization


Requirements

apt-get install squashfs-tools

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.

HOWTO

sudo puredyne.iso /mnt -o loop

mkdir extract-cd

rsync --exclude=/live/filesystem.squashfs -a /mnt/ extract-cd

sudo unsquashfs /mnt/live/filesystem.squashfs
sudo mv squashfs-root edit
sudo cp /etc/resolv.conf edit/etc/
sudo cp /etc/hosts edit/etc/

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

Just to be sure 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):

dbus-uuidgen > /var/lib/dbus/machine-id

dpkg-divert --local --rename --add /sbin/initctl
ln -s /bin/true /sbin/initctl

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

sudo umount edit/dev
sudo mv edit/packages.txt extract-cd/live/

Tasks to do

  • install all multilanguage documentation for programs and track they're directory if we can squash them or zip, inkscape,gimp,OOffice, some copies maybe from FOSS manuals?
  • remove unused themes
  • install some more open fonts
  • install some edubuntu software(find out which)
  • clean up desktop
  • boot and test the video software

<fruity> "aggiungere voce in syslinux menu per modo persistente"
<fruity> basta aprire syslinux.cfg o isolinux.cfg
<fruity> fare copia incolla della voce che hanno li gia
<fruity> editare il titolo e metterci "Persisten mode"
<fruity> e addare persistent a APPEND
<fruity> sai dove metti le opzioni del kernel

  • Remove all useless documentation from /usr/share/doc
  • Installed Openoffice suite
