Hi Sarah, When we are talking about the redesign, I often hear people mention about "modify DC so that it can work with xxxx" or "use DC to do xxxx". Some people are confused about what it really means. From what I read in the document, I feel that we are too focused on making DC work with AI, without talking about using it for other install components.
At a very high level, the functionalities provided by the DC are: - manifest parsing - checkpointing - the finalizer engine, to execute any scripts specified in the manifest - logging Manifest parsing and logging can be used by other install components, but the biggest functionality we want to "share" is the finalizer engine. Checkpointing is only applicable for DC, I think. So, what we really meant when we say "use DC to do xxxx" is the following: Enhance the finalizer engine, which is currently only used by DC, so that it is general enough for all other install components to use. Then, create/update finalizer scripts that can be plugged into this framework, and try to make the finalizer scripts to be reusable by different install components. Finally, modify existing AI and DC to use this enhanced finalizer engine, and use many shared finalizer scripts. This flexible execution engine can also be used by other existing or future install components, for example, even the slim installer.
