[chef] Re: Re: how to alter a recipe in the simplest, DRYest way?

Joshua,

 Thanks.  I'll try that.  But I humbly submit that Chef can do  
better.  DRY, DRY, DRY.  It'd be great to have syntax like:

    append_attribute "nginx" => {"configure_flags" =>  "--with- 
http_realip_module"}

(That's probably not what it'd look like, but you get the idea.)

R.
