Introduction
Image building will be performed with ubuntu-defaults-builder tools. The Italian team developed some side tools for simplifying the debugging and test procedures, since the ubuntu-defaults-image command builds the image every time from scratch and takes about one hour.
Image building
Install ubuntu-defaults-builder and dpkg-dev packages. Italian image will be create using defaults from ubuntu-defaults-it package available through a PPA.
For creating a i386 image run the following command:
$ ubuntu-defaults-image --ppa ubuntu-defaults-it-team/ubuntu-defaults-it --locale it --components main,restricted,universe --release precise --arch i386
For sharing the image you will need also to use the md5sum command for calculating md5 and the apt://zsync package for allowing people to download only the changes in you image with zsync.
Additional tools
All the additional tools are available through bazaar.
ubuntu-defaults-binary
Builds the image starting from a chroot created with a previous ubuntu-defaults-image step. It needs a cleaning step before, that can be performed manually with the ubuntu-defaults-binary-clean command or automatically if by ubuntu-defaults-binary itself.
ubuntu-defaults-binary-clean
Cleans the directory where ubuntu-defaults-image created the ISO image allowing to work manually inside the chroot for troubleshooting and creating a new image with ubuntu-defaults-binary step.
