Add a simple way to add/remove packages with the network state.

Use:
network:
pkgs:
    purged:
      - resolvconf
    installed:
      - isc-dhcp-client

network/packages.sls

+#!jinja|yaml
+
+{% for action, pkgs in salt['pillar.get']('network:pkgs', {}).iteritems() %}
+network_pkgs_{{ action }}:
+  pkg.{{ action }}:
+    - pkgs: {{ pkgs }}
+{% endfor %}

pillar.example.sls

           netmask: 255.255.0.0
           gateway: 192.168.2.1
 
+  # To add/remove packages here.
+  # You need to include the state network.packages in your salt.
+  pkgs:
+    purged:
