Yeah, that's a good typo, 3.1 it is.

True, you say, slice 1 is a FreeBSD slice. I am building a bootable  
CF. I hope it will suffice to say that my NetBSD machine is a  
diskless server and the diskless client is building a file image  
(with vnd) and then I wanted to write it to the CF with the Card  
reader I have on the NetBSD side. I hope that is clear!
