harddisc preparation for netwinder

Hello,

I want to install NetBSD on my netwinder.

I already have another ARM-based NetBSD system up and running.

Is it sufficient to put a new harddisc in my Shark, disklabel and newfs it and 
unpack the netwinder snapshot on it and move it afterwards in my netwinder 
box?

Or: do I need an ext2fs boot partition for the netwinder?

Are there any other problems associated with this way of installation?
