Using Drush in the application build cycle

Drupal deployments & workflows with version control, drush_make, and Aegir.

I'm not familiar with Aegir and this is a complicated issue, I was thinking about more granularly (is that a word) deploying modules using cvs and this technique which is a little more lightweight (and probably cheaper), but I could see where the other approach would have it's strengths.

As with any technology or process choice, there are pros and cons to each.

Clearly, again, the one take away from all of this is that drush is awesome.
