[lvm-devel] LVM2 ./WHATS_NEW doc/example.conf.in lib/confi ...



CVSROOT:	/cvs/lvm2
Module name:	LVM2

Log message:
	Require --restorefile when using pvcreate --uuid.
	
	Introduce --norestorefile to allow user to override the new requirement.
	
	This can also be overridden with "devices/require_restorefile_with_uuid"
	in lvm.conf -- however the default is 1.

+  Add --norestorefile option to pvcreate.
+  Require --restorefile when using pvcreate --uuid.
   Recognise and give preference to md device partitions (blkext major).
   Never scan internal LVM devices.
   Split-mirror operations were ignoring user-specified PVs.
