Ok, i try to unnderstand:
With lvcreate -s i create the snapshot. This creates an entry /dev/vgxxx/lvxxx.
Then i use kpartx for ... what ? Creating a second entry in /dev/... ?

I tested this:
created a snapshot /dev/vg1/lv_home_snapshot.
kpartx -lv  /dev/vg1/lv_home_snapshot says ... nothing.

Currently, i don't see the benefit of kpartx.
