As I wrote, Heartbeat supported mgmtd with defined MGMT_ENABLED, fails
to start with following without mgmtd executable.

Before it did not occure, because Heartbeat included all. As Pacemaker
and other tool Pacemaker-Python-GUI discreted, I am currently
confirming whether work or not well.

It is easy to support mgmtd with defining MGMT_ENABLE, but I feel that
there is a little danger for upper log. And I asked the resolving way.
