amvault to terteriary media

Is there anyone here making use of amvault, who has gotten amlabel to work?

My old, old recipe went something like this: amlabel -f 
-otapetype="LTO2" -otpchanger="" -olabelstr="Vault-[1-7]" 
-otapedev="/dev/nst0" vtl Vault-1 slot 1

But that doesn't work with the current amanda.conf format

Here's my /etc/amanda/vtl/amanda.conf, which vaults fine IF I have an 
already-labelled tape.  Note the difference between "storage" - which is 
vtl - and "vault-storage" which should be the LTO.
