FAQ
Hi.

I've done some googling, and did find something sort of similar in a
bug report (see http://projects.puppetlabs.com/issues/16082 and the
second to last update -- but as I created this post, I realize it's
almost certainly not related at all).

In a bunch of narrowing, I've found that apparently when you create
the resources using "create_resources" for the built-in type 'exec',
it completely ignores that 'command' argument. Here's that test:

foo.pp:
--------
$other = {
'/bin/false' => { command => '/bin/echo hello', },
}
create_resources('exec', $other)
--------

And the output from puppet apply foo.pp:

err: /Stage[main]//Exec[/bin/false]/returns: change from notrun to 0
failed: /bin/false returned 1 instead of one of [0]
notice: Finished catalog run in 0.29 seconds

Note that though the resource is created with a title of '/bin/false'
(according to the docs on puppetlabs.com), with the parameter
"command" set to '/bin/echo hello'. However, /bin/false is executed.

The command is NOT ignored if the resource is instantiated outside of
the create_resources() function:

foo.pp:
--------
exec { '/bin/false':
command => '/bin/echo hello'
}
--------

And the output from puppet apply foo.pp:

notice: /Stage[main]//Exec[/bin/false]/returns: executed successfully
notice: Finished catalog run in 0.32 seconds

In this case, the title is /bin/false, but the echo is called (or
true, or whatever you want to run).

Am I missing something, or is this a bug? It's an odd one as well,
because I *really* want to create titles that are arbitrary names, and
specify a command. Fortunately, the 'name' parameter, which is used
instead of 'command' if 'command' is not found, works.

Thanks for any help.

    I know this sounds odd, but what if you put command in quotes in your hash,
    like this:

    $stuff = { '/bin/false' => { 'command' => "/bin/echo 'hello there'" } }
    create_resources('exec', $stuff)

    This seems to work for me - does it work for you?

    Doesn't work here, puppet 3.0.1, rhel6...
