BLOCK

Block encapsulates a standalone entity that is meaningful on its own.

While blocks can be nested and interact with each other, semantically they remain equal; there is no precedence or hierarchy.

Holistic entities without DOM representation (such as controllers or models) can be blocks as well.

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.
