hi,

in the logs of our 2.7.10 puppet master we find messages like these:
Dynamic lookup of $functie at /etc/puppet/manifests/server_classes.pp:52 is 
deprecated. Support will be removed in Puppet 2.8. Use a fully-qualified 
variable name (e.g., $classname::variable) or parameterized classes.

However, I'm a bit worried that a key functionality will be removed in 2.8: 
we set a param/value in every node telling the node what it's funtion is 
and use that in a variety of manifests to decide how to configure the 
server.

we use something like:
node servera {
  $function = 'webserver'
  include function_dependent_services
}
node serverb {
  $function = 'dbserver'
  include function_dependent_services
}

class function_dependent_services {
  include iptables
  include motd
}

class iptables {
  file {
   "/etc/iptables/cfg-firewall":
     content => template("iptables/cfg-firewall.erb");
  }
}

and then, somewhere in the erb we evaluate <%= function %>

will this be broken in 2.8?
and, if yes: how should we tell the erb the param that changes for a lot of 
nodes?

or should I file this as a bug for v2.8?

please help us out, thanks in advance
Alex
