[chef] Re: Re: Re: including erubis fragments within a template

Mikes,

afaict, it won't work if you have any ruby in the included templates. You could get aroung that by having a template resource in your main recipe for each included "template" but I think that is unnecessary verbosity.

Also, I have no idea how well different EJB containers handle the <xml:include> statement. Perhaps there are gotchas there that I am not aware of. Also, it's something I would rather not become an expert on :p

Ah - I think I like that approach better - it's very similar to the
/something.d/ method of inclusion - include something it it is there.

Bryan, thoughts?
