Changes by:	mornfall at sourceware.org	2007-10-03 15:00:52

Modified files:
	scripts        : lvm_dump.sh 

Log message:
	a) use dmsetup version to check for dmsetup, but if it fails, set
	DMSETUP=: to disable dmsetup checks (but let the script run
	nevertheless); warn the user if this is the case
	b) put the non-root and dmsetup warnings both at start and end of
	output
