+# We need this to be able to make decision of what style of package we are
+# working with: Debian style package (for example, it uses a nova-consoleproxy
+# package and not nova-novncproxy, or it has a openstack-dashboard-apache,
+# etc.), or just the Ubuntu style package.
+#
+# This is needed, because in some cases, we are using the Debian style packages
+# but running under Ubuntu. For example, that's the case when running with MOS
+# over Ubuntu. For this case, a manual override is provided, in the form of a
+# /etc/facter/facts.d/os_package_type.txt containing:
+# os_package_type=debian
+#
+# In all other cases, we can consider that we're using vanilia (ie: unmodified)
+# distribution packages, and we can set $::os_package_type depending on the
+# value of $::operatingsystem.
+#
+# Having the below snipets helps simplifying checks within individual project
+# manifests, so that we can just reuse $::os_package_type directly without
+# having to also check if it contains a value, then check for the content of
+# $::operatingsystem (ie: what's below factors the check once and for all).
