[linux-lvm] lvcreate snap with device mapper

There is a funny problem with lvcreate. When you create a snap, it
assumes the second element in the supplied path is a volume group. This
is untrue when the device mapper is used, and it is untrue (obviously)
if symbolic links to the block device are used.
The text in the attachment demonstrates what I mean.

I think it's a bad thing to use path names for determining what volume
group has to be used.

This is on debian/sarge i386 with LVM2 2.01.04-2 and kernel 2.6.11 with
dm_mod.ko and dm_snapshot.ko loaded.
