CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	zkabelac at sourceware.org	2011-01-28 10:19:00

Modified files:
	lib/config     : config.c 

Log message:
	Use memcpy and add error message
	
	strncpy (which check each byte for \0) is not need as we always copy
	the length size - so using memcpy is a bit cheaper.
	
	Add missing log_error message for failed allocation.
