coLinux

This script and work was based on Cobootstrap for Debian. The following procedure assumes you have a running Ubuntu/Debian system to create the image. Access to the internet to download the base system install packages is required. From your Ubuntu/Debian system:

Install the debootstrap utility

sudo apt-get install debootstrap

Save the above script into /tmp/cobootstrap, edit the UBUNTU_VERSION and CO_SIZE to your needs.

chroot $CO_MOUNT apt-get update
chroot $CO_MOUNT apt-get autoclean
chroot $CO_MOUNT passwd -d root

umount $CO_MOUNT/var/cache/apt/archives
umount $CO_MOUNT
echo Compressing image
gzip image
ls -la image.gz
exit 0

Then run:

cd /tmp
 sudo sh cobootstrap

You will get an image.gz that you can decompress and use with colinux.
NOTE: The eth0 is setup to DCHP assuming you will be using slirp for the eth0 network.
