System: NetBSD woffi 1.2G NetBSD 1.2G (WOFFI) #2: Tue Jul 1 10:13:43 EDT 1997 root@woffi:/local1/src/netbsd-current/src/sys/arch/i386/compile/WOFFI i386


>Description:
	
The geometry support added to the vnode disk driver apparently requires 
that vnconfig be run on the full disk partition d, not on the first 
partiton, which does result in:
vnconfig: /dev/rvnd0a: Device not configured

In addition, newfs expects a proper disk label on the vnode disk:
newfs: ioctl (WDINFO): No such process
newfs: /dev/rvnd0a: can't rewrite disk label

>How-To-Repeat:
	
try to build the distribution floppies:
$ cd /usr/src/distrib/i386/floppies
$ make
>Fix:
	
The patch below is probably not the correct way to fix this problem, but
it allowed me to create a working boot floppy. I am not happy about the mods 
to /etc/disktab, there must be a better way.
