Any way to have puppet notify me if any files are missing from a directory?

[Dan Pasacrita]

Hey everyone, first I want to say that I joined this community a few days ago and already you guys have been amazingly helpful.

One thing that's been puzzling me lately is how I can have puppet examine a directory, compare its contents against a source, but only notify you if anything is missing. I know I can have it automatically sync the contents with the following:

file { '/path/to/file':

                ensure => "directory",

                recurse => "remote",

                mode => 755,

                source => "/path/to/source",

}

But is there any way for it to just check the directory, and not move anything over? Maybe it can run an exec command if it doesn't find every file that it needs to? One thing I was looking at was the creates parameter, like this:

exec { "/bin/echo absent >> /home/dpasacrita/absent.txt ":

                creates => "/home/user_name/test_dir",

}

which will create a text file if the directory "test_dir" is absent. This works, but it can't check the contents, since there's no source to compare them to. So I don't think that's the right way to go about it.

Any ideas?

if you omit the 'source' parameter, Puppet will indeed only make sure
that the path in question does lead to a directory, create it if it is
missing (provided the parent directory does exist) or even change an
existing file/symlink into a directory (danger, Will Robinson).

Thanks dude, noop was exactly what I was looking for. I'm wondering why the Documentation doesn't point out this feature more, because I don't recall ever seeing it.
