Hello,

Our team is porting a project from OpenBSD to NetBSD and TFM, (having 
Read it) is not getting me through a hang up with the formatting of 
disk images under NetBSD 3.0 Release, x86 P4.

I follow these steps under OpenBSD to create and mount a 500MB disk image:

sudo dd if=/dev/zero of=/home/sysjail00.img bs=1024 count=500000
sudo vnconfig -c /dev/vnd0c /home/sysjail00.img
sudo newfs /dev/vnd0c
sudo fsck -y /dev/vnd0c
sudo mkdir /mnt/sysjail00/
sudo mount_ffs /dev/vnd0c /mnt/sysjail00/

Under NetBSD I get as far as:

sudo dd if=/dev/zero of=/home/sysjail00.img bs=1024 count=500000
sudo vnconfig vnd0 /home/sysjail00.img
... and
sudo newfs vnd0 fails. I have tried vnd0c and I see evidence on the 
net (in reference to memory, CD and CF images) that disklabel and 
perhaps fdisk may be required. I tried several disklabel variations 
but perhaps a manual disklabel edit is required? If so, what entries 
are required?

Appreciated,

Michael.
