+# Common code for recipes that modify the phosphor-mapper

+# Typically it is not desired to monitor all dbus traffic
+# on a system and as such, the phosphor-mapper has command
+# line options to control what path namespaces and dbus
+# interfaces it will keep track of.
+#
+# The Phosphor layer by default configures the mapper to
+# watch xyz.openbmc_project interfaces and paths only.  This
+# configuration file is intended to be inherited by
+# native recipes in other layers that wish to add namespaces
+# or interfaces to the mapper watchlist.
+
+# Add path namespaces to be monitored:
+# PHOSPHOR_MAPPER_NAMESPACE_append = " /foo/bar"
+
+# Add interfaces to be monitored:
+# PHOSPHOR_MAPPER_INTERFACE_append = " foo.bar"

+# Blacklist paths from being monitored:
+# PHOSPHOR_MAPPER_NAMESPACE_BLACKLIST_append = " /foo/bar/baz"
