# # Include OWASP ModSecurity CRS rules if installed
# IncludeOptional /usr/share/modsecurity-crs/owasp-crs*.load
# The directory /usr/share/modsecurity-crs is shipped by the
# modsecurity-crs package, but it's only a Recommends: of
# libapache2-mod-security2, so it doesn'get installed. And IncludeOptional
# is only optional for the full path, so if /usr/share/modsecurity-crs doesn't
# exist, it bails out and apache refuses to start/restart. As such, ship an
# empty directory to make that include truly optional
# In addition IncludeOptional expects a wildcard (which the original config
# from modsecurity-crs doesn't ship, so we also need to ship an empty
# stub config
