Description
Fetch your favorite iso, in the following examples we will take Linux Mint 14.1 iso but this procedures can apply to a lot of different iso/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);
- 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
You can cut'n paste from here to your shell, as you need. 
# CREATING THE DEVELOPMENT SYSTEM FROM THE ISO IMAGE # we choose pd/ as our working directory, so... mkdir pd cd pd sudo mount linuxmint-14.1-mate-dvd-32bit.iso /mnt -o loop mkdir extract-cd rsync --exclude=/casper/filesystem.squashfs -a /mnt/ extract-cd sudo unsquashfs /mnt/casper/filesystem.squashfs sudo mv squashfs-root edit # ISO IMAGE CREATED! # USE YOUR DEVELOPMENT SYSTEM # 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!
NOTE: if the above dpkg-divert fail with a "not allowed" message, just remove /sbin/initctl.distrib
rm /sbin/initctl dpkg-divert --local --rename --add /sbin/initctl ln -s /bin/true /sbin/initctl
That's all folks!
Suggestions
font console setup:
wopr ~ # dpkg-reconfigure console-setup
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.

Hints
- Remove all useless documentation from /usr/share/doc
Splash screen: si trova in nella sezione extract-cd del kit di sviluppo, quindi fuori da edit/ : nel mio caso sta dentro /home/asbesto/Desktop/src/pd/extract-cd/isolinux e si chiama ovviamente splash.png, 640x480. SISTEMATO, VEDIAMO SE VA. CI SONO ANCHE ALTRI SFONDI DA PROVARE LI DENTRO.
Splash screen 2: usr/share/images/desktop-base/grubsplash-logo-simple.png settato a Volcan.png per grub, usato da /etc/grub.d/05_debian_theme.
Settare l'editor default da console
Si usa update-alternatives --config editor che ti fa scegliere l'editor preferito tramite un menu.
