Unified Installer with Buildout

An experimental version of the Unified Installer Plus Buildout is 
available for testing at:

https://launchpad.net/plone/3.0/3.0.4/+download/Plone-3.0.4-UnifiedInstallerBuildout-a1.tar.gz

This is an approximately 32 MB download.

Please file narrow bug report and feature requests to 
dev.plone.org/plone, marking the component as "Installer (Unified)" and 
specifying the UI+Buildout.

More general discussion, including evaluations of the concept and 
implementation, can be on the list, or as comments to PLIP #209 
<http://plone.org/products/plone/roadmap/209>.

Motivation for doing this:

The big hurdle that the Unified Installer gets many users over is the 
building of a Python -- complete with PIL, libjpeg, and libz interfaces 
-- that will work with Zope and Python. However, users with Unified 
Installer builds face a problem when it comes to adding egg-based 
products as they won't have the easy facilities for adding eggs and zcml 
provided by buildout. Also, minor-version migration is painful for 
Unified Installer users. They must install the new update and copy over 
their data and custom packages. In a buildout environment, they'd be 
able to just run bin/buildout.

Current implementation:

This test version includes all the eggs and downloadables required for 
Plone 3.0.4 so that it will run off-line. (A version that would pick 
them up online could be as small as 11MB.)

The initial build phase is the same as the Unified Installer: it builds 
Python 2.4.4 and PIL (and, optionally, libz and libjpeg) and creates a 
plone user if run as root. ZopeSkel and all its dependencies are also built.

In the next phase, a buildout template (different for zeo and 
standalone) is copied into place along with the egg/download cache. 
"buildout -No" is then run to finish up.

Some of the cleanup work that used to be done with shell scripts is now 
done with a plone.recipe.unifiedinstaller recipe (included as an egg; 
this is not yet on PyPI). plone.recipe.command is used to set ownership 
for root installs.

I look forward to your feedback and collaboration!

Steve
