How (and whether) to populate rails application with initial data

Question

For users and groups, the question of pre-existing users should be defined with respect to the needs of the application rather than the contingencies of programming. Perhaps your app requires an administrator; then prepopulate. Or perhaps not - then add code to gracefully ask for a user setup at application launch time.

On the more general question, it is clear that many Rails Apps can benefit from pre-populated date. For example, a US address holding application may as well contain all the States and their abbreviations. For these cases, migrations are your friend, I believe.
