Puppet users - Feb 2007 - Use of variables in defines...

Hi,

I''m banging my head against the usage of variables i defines. Fx. I  
have this defined to easily create new systemusers:

define systemuser($home = $home, $shell = "/bin/bash") {
     group { $name:
         ensure  => present
     }
     user { $name:
         ensure  => present,
         gid     => $name,
         home    => $home,
         shell   => $shell,
         require => Group[$name]
     }
     file { "$home":
         ensure  => directory,
         owner   => $name,
         group   => $name,
         mode    => 755,
         require => User[$name]
     }
     file { "$home/.ssh":
         ensure  => directory,
         owner   => $name,
         group   => $name,
         mode    => 700,
         require => File[$home]
     }
     remotefile { "$home/.ssh/authorized_keys":
         source  => "sshkeys/$name",
         mode    => 600,
         owner   => $name,
         group   => $name,
         require => File[$home]
     }
}

I can call it with:

systemuser { newusername:
	home    => "/home/newusername"
}

remotefile is a previously defined resource. So I''m using a defined  
resource inside a new defined resource. It works fine, creates the  
user, group, homedir, ssh dir, and authorized_keys file. But it seems  
that I can''t say:

source	=> "sshkeys/$name_rsa.pub"

in the remotefile statement - puppet can''t find the file then.
It''s
not a big deal, but it''s annoying and prone to errors that is hard to  
track down.

How can variables be used in ways like this? Are there any restrictions?

In that case, puppet looks for a variable ''name_rsa''; AFAIK,
what you
want is
        source	=> "sshkeys/${name}_rsa.pub"
