At Drupalcon, there was all kind of talk around challenges like how to manage a collection of multisite installs, how to do things like run cron or update.php on 60 gazillion sites, how to enable/disable "packages" of modules/functionality to avoid having to click through 10,000 things, how to migrate database changes from one site to another, etc. I'm planning on spending a few hours this week trying out various Drupal packaging/site provisioning systems and writing up a report comparing/contrasting them. Here are the modules I know about in this space: http://drupal.org/project/patterns: Module/system configurations that can be run at any time http://drupal.org/project/hostmaster: Bryght's multisite hosting managed site deployment framework, which includes http://drupal.org/project/hosting and http://drupal.org/project/provision http://drupal.org/project/autopilot: Migrate changes from dev to live http://drupal.org/project/deploy: Migrate changes from dev to live http://drupal.org/project/drush: Command-line tool containing a bunch of useful commands such as running cron, downloading modules, etc. Any others I should be taking a look at? -Angie
