at this moment it still appears to be the documented way to do application setup, so either there should be a new documented best practice or this should be fixed. I just ran into the same problem (although it appears to break differently now) so I'ld expect this to be a fairly common issue. > The problem with setup-app is it can only do one thing, and that thing > may be wrong when copying an existing deployment or updating it.

I get the imporession that you are talking about migration types of usage here. That is a very different problem than initial application setup and is indeed best served differently, most likely in a way that is much closer tied to the specific application. Initial setup is simple and predictable in most cases: create a database, create some tables, load some initial data, maybe create a file and directory or two. websetup/paster setup-app seems to be a good standard way to do that. Perhaps it can be extended with a flag to make it refuse to run if it has been run before, which will prevent people from accidentily zapping existing data.
