CVSROOT:	/cvs/cluster
Module name:	cluster
Branch: 	RHEL5
Changes by:	teigland at sourceware.org	2007-02-09 16:05:39

Modified files:
	group/dlm_controld: dlm_daemon.h main.c 

Log message:
	clear configfs stuff if we get SIGTERM, this is a convenience if you
	want to kill dlm_controld and remove the dlm module without leaving
	the cluster.  Otherwise you have to manually clear configfs dirs.
