[chef] Re: Re: Application cookbook

["John E. Vincent (lusis)" < >]

We use a modified version of some of the application cookbook ideas
around here. Basically we have app specific cookbooks that allow us to
override the container and container version as attributes so we can
test our code on different containers fairly easily. There's still a
lot of duplicated code. We need to move more of the generic stuff into
a databag.

Waiting patiently to give Edmund's new stuff a shot.
