Here's how to assemble your own images with live-build running in a cross environment. This works for the nano, developer, alip and ubuntu-desktop images for p & q. I've also created a server image as well.
This does work for older oneiric based images with the exception of ubuntu-desktop due to a mono + qemu bug.
Install Required Packages
apt-get update apt-get install live-build apt-get install qemu-user-static
Configure and Build
mkdir dirforbld ; cd dirforbld #pick a branch: bzr branch lp:~linaro-maintainers/linaro/live-helper.config.precise.nano config # or: bzr branch lp:~linaro-maintainers/linaro/live-helper.config.precise.developer config # and so on. cp config/conf_create.sh . # add/remove packages listed in config/package-lists/nano.list.chroot which is a text file. One package per line. sh ./conf_create.sh lb build # When rebuilding use the commands : # lb clean --all ; lb clean --cache; rm -rf .stage/* ; lb build
