snapshot-resync-target-lvm.sh cannot create a thin snapshot

[ajschorr]

In snapshot-resync-target-lvm.sh, the snapshot is created like so:

lvcreate -s -n $SNAP_NAME -L ${SNAP_SIZE}k $LVC_OPTIONS $VG_NAME/$LV_NAME

Because of the -L option, the resulting snapshot will be a "thick" snapshot, even if the volume in question
is a thin volume. Is there some reason that it is done this way with no option for creating a thin
snapshot by omitting this argument?

Perhaps I'm missing something important, but it seems to me that there should be an option
to this script to omit the -L argument so that a thin snapshot could be used instead.
