I thought it would be helpful to update /etc/motd with the datestamp of the 
last policy update. I think its working as I expect, anyway in case someone 
else finds it useful.

#### templates/motd.tpl ####
#
# This server is managed by CFengine, any manual edits may be reverted.
# CFengine policy last updated: $(sys.date).
#

#### failsafe.cf ####
body common control{
    bundlesequence => { "update" };
    inputs => { "update.cf" };
}

body depth_search recurse(d){
    depth => "$(d)";
}

body edit_defaults empty{
    empty_file_before_editing => "true";
    edit_backup => "false";
    max_file_size => "300000";
}

bundle edit_line expand_template(templatefile){
# Read in the named text file and expand $(var)
# inside the file
insert_lines:
   "$(templatefile)"
        insert_type => "file",
            comment => "Expand variables in the template file",
     expand_scalars => "true";
}

#### update.cf ####
bundle agent update {
    vars:
        "policyhost" string => "192.168.1.129";

    files:
        any::
            "/var/cfengine/inputs/"
                copy_from    => 
update_policy("/var/cfengine/masterfiles","$(policyhost)"),
                classes      => policy_updated("policy_updated"),
                depth_search => recurse("inf");

        policy_updated::
            "/etc/motd"
                comment       => "Update /etc/issue with last policy update 
time",
                create        => "true",
                edit_defaults => empty,
                edit_line     => 
expand_template("/var/cfengine/inputs/templates/motd.tpl");
}


body copy_from update_policy(from,server){
    servers     => { "$(server)" };
    source      => "$(from)";
    purge       => "true";
    preserve    => "true";
    compare     => "digest";
}

body classes policy_updated(new_class){
    promise_kept     => { "$(new_class)" };
    promise_repaired => { "$(new_class)" };
}
