Puppet users - May 2013 - Two resources managing the same file?

Given a configuration file that is initially managed by a template in File 
resource A .  Resource B interacts with a middleware product through its 
published admin API which causes changes within File resource A.  Is there 
anyway, through custom provider code for resource B to tell resource A that 
its changes affect the configuration file so that when the state of 
resource A is checked it accounts for the changes made by B?

It seems to me that you will be relinquishing puppet''s ability to
maintain the content of the file by doing this. If that''s acceptable,
use the replace parameter to only have puppet maintain the initial config and
allow the file to be changed outside puppet moving forward. If that''s
not acceptable, then the location from which the template values are derived
must be updated in lock-step with the changes you make externally to puppet.
This may be possible programmatically depending on your scenario, but it feels
like the wrong direction to go to me.

I might approach this with a wrapper class that has awareness of resource A and
resource B, and feeds them both the proper parameters to satiate their needs
when cohabitating.

Alternatively, I might stub out a conf.d style config directory and provide to
resource B a handle into resource A''s config file through an included
config file owned by resource B.
