Pretty much, the devil-in-the-detail part is getting your merge
request in a state that makes it easy for a cookbook maintainer to
merge the whole set of changes or cherry pick only some coherent
parts.
If you are not very familiar with Git, e.g squash when rebasing, then
it may be easiest for you to do what Dan DeLeo suggests.  The cuken
and cookbooks account are really bleeding edge suck-it-and-see
exercises right now.
