-# 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 $::os['name']
-#
-# 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
-# $::os['family'] (ie: what's below factors the check once and for all).
