Nice to know ... we use the snapshot feature heavilyin our 
virtualization, but as: 
	CentOS 6 is at lvm2-2.02.100-8.el6.x86_64, and 
	C 5 at lvm2-2.02.88-12.el5, 

we will need to wait a bit before relying on its presence.  
Any chance of a re-basing / refresh / backport at least into 
RHEL 6 (we have only one Xen oriented dom0 at this point on 
C5)?

Thanks
