Puppet users - Jan 2012 - Conditionally replace in file type

Hello, I''m making the deployment of an application configuration as
follows:

  file {"/home/user/foo/bar":
    ensure  => directory,
    recurse => remote,
    source  => "puppet:///configs/${hostname}/home/user/foo/bar",
    ignore  => ["file1.cfg","file2.cfg"],
  }

I am ignoring these two files ("file1.cfg","file2.cfg"),
cause they are dynamically
modified by the application. So, not puppet managed.
And here''s my problem. Because on the other hand I have to initialize
both
files in the first run.

What can I do? Is there any way of mix "ignore" and
"replace" parameters?
PS: I cannot define other resource with the path of not-managed files, 
because depending on hostname that path changes.


Thanks in advance and apolgize my poor english!
;)

first application run?
How would you generally initialize them manually?

Asking to get better idea of the problem.

The right answer to these problems is almost always that you have a
`file { ".../foo": ensure => present }` resource in Puppet: that
will
put it in place if the file is not present, using whatever source you
give, but will not touch the content of an existing file.

If you are using a recursive file resource to put the rest of the
content in place around this, no problem, because the more specific
file resource will override the recursive one, and you won''t
overwrite. :)

Ok Daniel, thanks for your reply, but I have not control about these 
individual "noreplace" files because are $hostname dependent.
In different hostnames, have different source locations so I cannot define 
them in a specific way. 

E.g:

hostname1/home/user/foo/bar/johndoe05/file1.cfg
hostname2/home/user/foo/bar/maryjoe02/file1.cfg


That was the reason for I need something recursive, similar to ignore 
parameter. (Or a workaround)

Thanks!

Generally, what we would encourage is then that you define them on a
per-hostname basis.  You can do that at the node level, or you can
push that down through a define or parameterized class, but the key is
to model that - on a per host basis.

I assume you meant "they are different on every host", rather than
literally being a file with the hostname in it; for that you could
just go with `file { "/path/to/${hostname}.cfg": ... }` to define the
files. :)

Define them per-node. :)

node hostname1 {
  # define it in the node
  include common::stuff
  file { "/home/user/foo/bar/johndoe05/file1.cfg": ... }
  # use a parameterized class
  class { "something::else": configpath =>
"/home/user/foo/bar/johndoe05" }
  # ...or a define.
  some::define { "whatever": configpath =>
"/home/user/foo/bar/johndoe05" }
}
