View an install.img file

[Bob Bernstein <poobah%ruptured-duck.com@localhost>]

I have grabbed NetBSD-9.99.88-amd64-install.img.gz from 
http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/images/ and 
gunzipped it.

I thought to mount it for viewing before writing it to my USB 
stick.

Shouldn't pester a busy vnode:
$ sudo vnconfig -l
vnd0: not in use
vnd1: not in use
vnd2: not in use
vnd3: not in use

Create a vnode:
$ sudo vnconfig -c vnd0 ~/NetBSD-9.99.88-amd64-install.img

Now I run aground:
$ sudo mount -t msdos /dev/vnd0a /mnt
mount: no match for `vnd0a': No such process

I am of course guessing at 'msdos' AND vnd0a! The Guide provides 
examples for iso images but I don't see any for "install.img".

Any help would be super.

Thank you.
