+# The CRUSH location consists of a list of key=value pairs, separated
+# by spaces, all on a single line.  This describes where in CRUSH
+# 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.
