# Rules specific to Debian systems.  Try to keep this rule set to an absolute
# minimum.  Part of the goal of Puppet is to make our systems look as similar
# as possible given the inherent differences between the distributions, and
# that means that changes should be wrapped in conceptual packages that do
# equivalent things on both distributions.  This should hold only those things
# that configure a Debian OS as such, as distinct from Red Hat.
