Module name:	LVM2
Changes by:	zkabelac@sourceware.org	2012-01-20 11:01:13

Modified files:
	lib/format_text: archiver.c 

Log message:
	Thin until proper vgcfgrestore for thin is implementad, disable restore.
	
	Since it may probably do more harm to leave it enabled - add extra test
	for presence of thin volumes in VG, and in this case disable restore.
