>Description:
	dump saves all files with changend m-time or changed c-time.
	Large files, where only c-time is changed, e.g. mailfolders, databases
	etc. will be saved day after day allthough the content of the 
	files did not change.
	
>How-To-Repeat:
	
>Fix:
	ignore c-time anyway because there is no need to save files where only 
	the status has changed or
	add another flag to dump and ignore c-time, based on this flag.

	A solution/workaround is to ignore c-time in the CHANGEDSINCE-macro 
	in /usr/src/sbin/dump/traverse.c

/* Auxiliary macro to pick up files changed since previous dump. */
 #define CHANGEDSINCE(dp, t) \
-       ((dp)->di_mtime >= (t) || (dp)->di_ctime >= (t))
+       ((dp)->di_mtime >= (t))
