| I am the Lorax.  I speak for the trees [and images].
 | |
| 
 | |
| Tree building tools such as pungi and revisor rely on 'buildinstall' in
 | |
| 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.
 | |
| 
 | |
| 
 | |
| EXISTING WORKFLOW:
 | |
| 
 | |
| pungi and other tools call scripts/buildinstall, which in turn call other
 | |
| scripts to do the image building and data generation.  Here's how it
 | |
| currently looks:
 | |
| 
 | |
|    -> buildinstall
 | |
|        * process command line options
 | |
|        * write temporary yum.conf to point to correct repo
 | |
|        * find anaconda release RPM
 | |
|        * unpack RPM, pull in those versions of upd-instroot, mk-images,
 | |
|          maketreeinfo.py, makestamp.py, and buildinstall
 | |
| 
 | |
|        -> call upd-instroot
 | |
| 
 | |
|        -> call maketreeinfo.py
 | |
| 
 | |
|        -> call mk-images (which figures out which mk-images.ARCH to call)
 | |
| 
 | |
|        -> call makestamp.py
 | |
| 
 | |
|        * clean up
 | |
| 
 | |
| 
 | |
| PROBLEMS:
 | |
| 
 | |
| 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
 | |
| it's not completely clear from reading the scripts.
 | |
| 
 | |
| 
 | |
| NEW IDEAS:
 | |
| 
 | |
| 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.
