can be dynamically loaded via the live component replacement service. Sync handlers are also dynamically contributed. It is possible to build using either dynamic loading via LCR or static linking of the entire executive. This is controlled by the BUILD_DYNAMIC configuration option in the Makefile. git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@892 fd59a12c-fef9-0310-b244-a6a79926bd2f
