Description

On 4.1.20 on SLES11:

I have an NCF methods that starts/stops a service (lldpd) based on the presence/absence of a class.

There is a group-based class the node either belongs to or does not belong to:

# cf-promises --show-classes | grep lld
group_lldpd_enabled                                          source=promise,inventory,attribute_name=rudder_groups

There is an NCF Method that consists of starting+enabling or stopping+disabling the service depending on the class:

bundle agent service_test
{
  vars:
    "class_prefix" string => canonify(join("_", "this.callers_promisers"));

  methods:
    "method_call" usebundle => service_ensure_started_at_boot("lldpd"),
      ifvarclass => concat("any.(group_lldpd_enabled)");
    "method_call" usebundle => service_ensure_running("lldpd"),
      ifvarclass => concat("any.(group_lldpd_enabled)");
    "method_call" usebundle => service_ensure_stopped("lldpd"),
      ifvarclass => concat("any.(!group_lldpd_enabled)");
    "method_call" usebundle => service_ensure_disabled_at_boot("lldpd"),
      ifvarclass => concat("any.(!group_lldpd_enabled)");
}

Same in NCF:

Now depending on the class, one half of those 4 promises are always missing reports:

Is this by design, a bug, or just user error?
