[chef] Re: Re: Inserting files into templates

[Nick Bryant < >]

Hey Jek,

Thanks for the response. You hit the nail on the head, the template
was being evaluated when the variable had no content...

I tried using 'action: nothing' in the template and doing a 'notifies:
create' from the ruby block, but sadly it still didn't work.

Seems putting dynamic content into the template resource is pretty difficult!

Thanks anyhow,

Nick
