Ok thanks. I found some better docs on the callbacks under the Deploy resource http://wiki.opscode.com/display/chef/Deploy+Resource - this probably should be referenced in the Application cookbook. I'll probably use before_restart or similar.

The other thing I want to do is override the unicorn and runit templates (to implement the structure used by github https://github.com/blog/517-unicorn). Ideally, I could still use the unicorn block as normal. I'm kind of new to Chef but can I just place sv-unicorn-run.erb (for the application_ruby unicorn resource) and unicorn.rb.erb (for the unicorn cookbook) within redmine/templates/defaults or do the underlying templates need a "cookbook" parameter in which case they would need modifications?
