So PREINSTALL is before DESCRIBE.
And it does this:

  |       BeanMetaData metaData = context.getBeanMetaData();
  |       if (metaData.getBean() != null)
  |       {
  |          BeanInfo info = configurator.getBeanInfo(metaData);
  |          context.setBeanInfo(info);
  | 
  |          MetaData md = addMetaData(context);
  | 
+ sets up new child Controller (if there is a scoping annotation on the bean).

But the rest of the dependencies:

  |          try
  |          {
  |             DependencyInfo depends = context.getDependencyInfo();
  |             // add custom dependencies (e.g. AOP layer).
  |             List<Object> dependencies = info.getDependencies(md);
  |             log.trace("Extra dependencies for " + context.getName() + " " + dependencies);
  |             if (dependencies != null)
  |             {
  |                for (Object dependencyName : dependencies)
  |                {
  |                   AbstractDependencyItem dependency = new AbstractDependencyItem(metaData.getName(), dependencyName, ControllerState.INSTANTIATED, ControllerState.INSTALLED);
  |                   depends.addIDependOn(dependency);
  |                }
  |             }
  |          }
  |          catch (Throwable t)
  |          {
  |             removeMetaData(context);
  |             throw t;
  |          }
  | 
are still done in DescribeAction, right.
