+# hierarhcy this entity should be placed.
+#
+# Arguments:
+# --cluster <clustername> name of the cluster (see /etc/ceph/$cluster.conf)
+# --type <osd|mds|client> daemon/entity type
+# --id <id> id (osd number, mds name, client name)
+#
+
+# if we start up as ./ceph-crush-location, assume everything else is
+# in the current directory too.
