Puppet users - May 2010 - Checking for files on the client?

Hi all,

I''m looking for a way to run an exec statement if a file does not exist
on the server is this possible?

Example code:

===================
define yumrepo(srcpkg = "",name = "")

if(!exists("/etc/yum.repos.d/${name}.repo")) {

	if($srcpkg != "")
		{
			exec{"rpm -Uh ${srcpkg}"},
		}
}
else
{
	file { ''/etc/yum.repos.d/${name}.repo'':
		source => "puppet:///modules/yumrepos/${name}.repo",
	}
}

=================
The idea is that if a repo is requested but the appropriate file does
not exist it is installed from the repo''s RPM (where possible)
otherwise
a file is pushed from the puppetmaster.

What I want to avoid is the repo RPM being installed at every puppet run
whilst also avoiding the need to push GPG keys (some of which are only
available via the repo''s RPM as far as I can tell...)

If someone could give me some pointers, that would be great!

Thanks in advance,

Matt

I''ve been thinking about this some more as I''ve been
developing this
module for easy install of RPM repos.

Would it work if I pushed out a custom fact with the repo that I then
called in the manifest?

Example (pseudo-code!):

=============if(!fact->$repoName){
	install repo from rpm
}
else
{
	check repo config against file
}
===========
I''m not convinced that this fixes everything but I think it might do
the
trick.

Thoughts?

M.
