< p > I am the Lorax. I speak for the trees [and images].< / p >
< p > Lorax is used to build the Anaconda Installer boot.iso, it consists of a
library, pylorax, a set of templates, and the lorax script. Its operation
is driven by a customized set of Mako templates that lists the packages
to be installed, steps to execute to remove unneeded files, and creation
of the iso for all of the supported architectures.< / p >

< p > Tree building tools such as pungi and revisor rely on ‘ ’

anaconda/scripts/ to produce the boot images and other such control files
in the final tree. The existing buildinstall scripts written in a mix of
bash and Python are unmaintainable. Lorax is an attempt to replace them
with something more flexible.< / p >

< p > PROBLEMS:< / p >
< p > The existing workflow presents some problems with maintaining the scripts.
First, almost all knowledge of what goes in to the stage 1 and stage 2
images lives in upd-instroot. The mk-images* scripts copy things from the
root created by upd-instroot in order to build the stage 1 image, though

< p > NEW IDEAS:< / p >
< p > Create a new central driver with all information living in Python modules.
Configuration files will provide the knowledge previously contained in the
upd-instroot and mk-images* scripts.< / p >
