Hi,

in a role, I have:

- name: Install packages, needed for named  
&nbsp;&nbsp;pkgng:  
&nbsp;&nbsp;&nbsp;&nbsp;name: "{{ lr\_bind9\_pkg }}"  
&nbsp;&nbsp;&nbsp;&nbsp;state: latest  
&nbsp;&nbsp;&nbsp;&nbsp;register: testresult

I want to trigger a reload of named, if pkgng has changed something.  
As pkgng does not have a notify attribute, I tried:

- name schedule reload if pkg installed/upgraded  
&nbsp;&nbsp;notify Restart named  
&nbsp;&nbsp;&nbsp;&nbsp;when: testresult.changed

But notify does not allow „when“.

What is the solution for my problem?

Axel

Hello Axel,

as far as I know "notify" is a generic task parameter and not related to the module you are using.

The same goes for register.

- name: Install packages, needed for named  
&nbsp;&nbsp;pkgng:  
&nbsp;&nbsp;&nbsp;&nbsp;name: "{{ lr\_bind9\_pkg }}"  
&nbsp;&nbsp;&nbsp;&nbsp;state: latest  
&nbsp;&nbsp;register: testresult  
&nbsp;&nbsp;notify: reload named

Or you add a "service" task which ensures that named is restarted.

Hello Racke,

> as far as I know “notify” is a generic task parameter and not related to the module you are using.

Ah, yes, as task parameter, it works:

- name: Install packages, needed for named  
pkgng:  
name: “{{ lr\_bind9\_pkg }}”  
state: latest  
notify:  
Restart named

Thanks, Axel
