From bb52fc2774ef690d6bb951fe9cc34e5b373caffe Mon Sep 17 00:00:00 2001 From: Jan Friesse Date: Mon, 13 Oct 2014 11:58:58 +0200 Subject: [PATCH] Store configuration values used by totem to cmap Some totem configuration values (like token, consensus, ...) are ether computed or default value is used. It's hard to find out, what value is really used. Solution is to store values in cmap.
