Unicorn that receives USR2 signal on upstart's "stop unicorn", but also allows upstart to respawn it when for some reason it crashed on its own.

Upstart config for a Rails app using Unicorn HTTP server

Using Unicorn with Upstart

This configuration works with Upstart on Ubuntu 12.04 LTS

The reason why it needs to be done this way (i.e. with the pre-start and post-stop stanzas), is because Upstart is unable to track whever Unicorn master process re-execs itself on hot deploys. One can use it without hot-deploys and run Unicorn in foreground also, it then only needs one exec stanza.

This presumes you are not using RVM, so no voodoo dances.
