--> NAME
-->      dump - filesystem backup
--> 
--> SYNOPSIS
-->      dump [0123456789BbhfusTdWn [argument ...]] filesystem
-->      dump [0123456789BbhfusTdWn [argument ...]] directory
-->

--> It *can* do it,

Not on Linux.  The Linux version accepts a directory name as a
convenient shorthand, but dumps the whole filesystem containing
that directory:

	bash# dump 0f /dev/null /etc
	  DUMP: Date of this level 0 dump: Tue Mar 23 01:17:42 1999
	  DUMP: Date of last level 0 dump: the epoch
	  DUMP: Dumping /dev/sdb1 (/) to /dev/null
	  DUMP: mapping (Pass I) [regular files]
	  DUMP: mapping (Pass II) [directories]
	  DUMP: estimated 2342 tape blocks on 0.06 tape(s).
	  DUMP: dumping (Pass III) [directories]
	  DUMP: dumping (Pass IV) [regular files]
	  DUMP: DUMP: 2276 tape blocks on 1 volumes(s)
	  DUMP: Closing /dev/null
	  DUMP: DUMP IS DONE
	bash#

P.S. We've probably overstayed our welcome for backup issues using
     this mailing list ... perhaps we should take further dump
     discussions offline.
