Puppet users - Feb 2009 - Overriding files specified in modules

Can I override files specified in a module on a per-client basis?

Suppose I have a module that is to be installed on a large number of
clients, and one of the files it provides is /x/y/z. One a very small
number of clients, that file needs to be slightly modified. What I want to
do in the module, ideally, is something like:

	file { "/x/y/z":
		if (file puppet:///mymodule/$fqdn/z exists:
			source => puppet:///mymodule/$fqdn/z
		else:
			source => puppet:///mymodule/z

Is there a way to achieve that?

Thanks,
Keith

from: http://reductivelabs.com/trac/puppet/wiki/TypeReference#file  
under source:

"If you specify multiple file sources for a file, then the first  
source that exists will be used. This allows you to specify what  
amount to search paths for files:"

file { "/path/to/my/file":
     source => [
         "/nfs/files/file.$host",
         "/nfs/files/file.$operatingsystem",
         "/nfs/files/file"
     ]
}


this seems to be your solution.
