Bug#550100: Snapshot creation results in symlink to COW, not snapshot

[Sharif Ibrahim]

Package: lvm2
Version: 2.02.53-1

# lvcreate --snapshot --name home_snap --size 100M /dev/cryptvg/home
  Logical volume "home_snap" created
# readlink /dev/cryptvg/home_snap
../mapper/cryptvg-home_snap-cow

In previous versions, home_snap was a symlink to cryptvg-home_snap instead 
of cryptvg-home_snap-cow.  In particular, it is no longer possible to 
mount a snapshot via the symlink since it is pointing to the wrong device.
