I'm working on a policy for global & local cron entries. I know it's easier to 
manage the whole file but I can't in this instance. The objective is to have 
global entries across all hosts, then if a specific entry is need for a host, 
define it in an slist named local_root_cron_entries_to_add

Here is the policy:-



########################################################
body common control
{
any::
  bundlesequence  => {
                     manage_cron
                     };
  inputs          => {
                     "/tmp/cfengine_stdlib.cf"
                     };
}

########################################################
bundle agent manage_cron {

vars:

   "global_root_cron_entries_to_add" slist => {
                                        "0 0 * * 6 /usr/local/bin/do_savevg.sh 
> /dev/null 2>&1"
                                        };

   any::

        "all_entries_to_be_added" slist => {
                                "@(global_root_cron_entries_to_add)",
                                "@(local_root_cron_entries_to_add)",
        }, policy => "ifdefined";

        "all_entries_to_be_removed" slist => {
                                "@(global_root_cron_entries_to_remove)",
                                "@(local_root_cron_entries_to_remove)",
        }, policy => "ifdefined";

files:

  # root crontab location defined in vars above
  "/tmp/root_cron"

        comment      => "Manage the contents of root cron ",
        handle       => "root_cron_entries",
        create       => "true",
        classes      => if_repaired("root_cron_repaired"),
        edit_line    => 
append_if_no_lines_and_delete("@{manage_cron.all_entries_to_be_added}","@{manage_cron.all_entries_to_be_removed}");

#commands:

#  root_cron_repaired::

#        "/usr/bin/crontab $(crontab)";

}

bundle edit_line append_if_no_lines_and_delete(lines_to_add,lines_to_delete)
{

insert_lines:

        "$(lines_to_add)"

                comment => "Append lines to the file if they don't already 
exist";

delete_lines:

        ".*$(lines_to_delete).*"

                comment => "Append lines to the file if they don't already 
exist";


}


I'm getting the following in my file:-



root@****:/tmp # cat root_cron
0 0 * * 6 /usr/local/bin/do_savevg.sh > /dev/null 2>&1
cf_null


Shouldn't the cf_null entry be removed as I have the ifdefined statement? I'm 
using version 3.2.3.

Cheers
