If you make an SLS file as such:

{% if grains['os_family'] == 'Suse' %}
{% if grains['osrelease_info'].0 == '42' %}
/etc/zypp/repos.d/home_osynge_vmcatcher.repo:
  file:
    - managed
    - source:
        - salt://jenkins-swarm/home:osynge:vmcatcher.repo
    - user: root
    - group: root
    - mode: 600
    - makedirs: False

{% endif %}
{% endif %}
{% if grains['os'] == 'openSUSE Leap' %}
{% if grains['osrelease_info'].0 == '42' %}
/etc/zypp/repos.d/home_osynge_vmcatcher.repo:
  file:
    - managed
    - source:
        - salt://jenkins-swarm/home:osynge:vmcatcher.repo
    - user: root
    - group: root
    - mode: 600
    - makedirs: False
{% endif %}
{% endif %}
{% if grains['os'] == 'openSUSE Leap' %}
/etc/zypp/repos.d/home_osynge_vmcatcher.repo:
  file:
    - managed
    - source:
        - salt://jenkins-swarm/home:osynge:vmcatcher.repo
    - user: root
    - group: root
    - mode: 600
    - makedirs: False
{% endif %}

It should error as duplicate states as all these filters match on LEAP.

SO the bugs are that 

{% if grains['os_family'] == 'Suse' %}

Does not work on LEAP.

and that 

{% if grains['osrelease_info'].0 == '42' %}

Does not work on LEAP.

Corresponding solutions work for redhat closes such as Scientific Linux.
