Puppet users - May 2013 - How to have one file depend on many packages

Here''s a puzzler (though I''m sure the answer is obvious and
I''m just not
seeing it):

I have a manifest where I''m listing about 40-50 packages that I want
the
system to remove, and a file that I want to create only after successful 
removal of all the packages.

What''s the best way to show this dependency so that the file is only 
created after all the packages are removed?

Thanks!


Bret

The simplest method is to use the ''before'' metaparameter in
each of the package resources that must be synced before you want the file
created. E.g.

package { [ "a", "b", "c" ]:
    ensure => absent,
    before => File["/some/file"],
}

file { "/some/file":
    ensure  => file,
    content => "Where did all the packages go?",
}
