I am fairly new to Ansible and having a problem with a playbook in which I 
wish to have a handler run one script if the target OS is in the RedHat 
family and another script if the target OS is in the Debian family.  I am 
clearly doing this wrong.  Here's the relevant snippet:

[...]
  handlers:
    - name: restart foo
      shell: /etc/init.d/barfoo stop ; /etc/init.d/barfoo start
      when: ansible_os_family == "RedHat"
      shell: /etc/init.d/bazfooinit stop ; /etc/init.dbazfooinit start
      when: ansible_os_family == "Debian"
[...]

This works fine for the targets running a Debian distro (in this case two 
Debians and an Ubuntu) but does not work. for the hosts running a Red Hat 
distro (actually three CentOS servers, all running the same version of 
CentOS).  The handler just returns "skipping: [<host>]" for each CentOS 
host.

Running ansible against those targets with -m setup -a 
'filter=ansible_os_family' returns the expected "RedHat" for the CentOS 
hosts.

I suspect I am doing something wrong.  Is it not possible to have two 
"when:" statements and only the last one is interpreted?  That would seem 
to explain what I am seeing.  If that, or something similar is the case how 
can I accomplish what I need to do... kind of a "if RedHat, elseif Debian" 
sort of behavior?

Thanks!
