Just some quick links!
This links describes how to manage multiple databases with Capistrano. That’s not why I picked it though. I liked it because it shows the “<<: *” syntax of yaml.
And a repository of Ubuntu Hardy Heron debs for mod_rails/Phusion passenger. At this time I installed mod_rails via rubygems. But if the guys at brighbox make the package so it builds/installs the Apache module automatically (without human intervention and pressing Y two times) I will install that one. Much, much nicer to use with Puppet.
