Rudder

Note: we already have several bodies available in the rudder_stdlib.cf to help with this:

body edit_defaults rudder_empty_select(select)
{
        empty_file_before_editing => "${select}";
        max_file_size             => "1024000";
        edit_backup               => "timestamp";                                                                                                                       
}

body edit_defaults noempty_backup
{
        empty_file_before_editing => "false";
        edit_backup               => "timestamp";  # we want to keep a track of everything                                                                              
        max_file_size             => "1024000";
}

body edit_defaults empty_backup
{
        empty_file_before_editing => "true";
        edit_backup               => "timestamp";
        max_file_size             => "1024000";
}

And for copy_from, one in cfengine_stdlib.cf:

body copy_from backup_local_cp(from)
# Local copy, keeping a backup of old versions
{
        source      => "$(from)";
        copy_backup => "timestamp";                                                                                                                                     
}
