Bruce Lane asked the question as to why there wasn't a copy of boot.fs 
available for tape installs. I have attempted to create one. This image is 
here:
	<http://www.mcmanis.com/~cmcmanis/boot.img.gz>
(note to Bruce this is a new one since the one you tried)

I followed the following steps:
	1) Create a "blank" file using:
		dd if=/dev/zero of=boot.img bs=512 count=4096
	2) Make it a virtual disk
		vnconfig /dev/vnd0c boot.img
	3) Create a file system on it:
		newfs -i 16384 /dev/vnd0c
	4) But the first stage booter on it:
		disklabel -B -b /usr/mdec/xxboot /dev/vnd0c
	5) Mount it for use:
		mount /dev/vnd0c /mnt
	6) Put boot and the install kernel on it.
		cp /boot /mnt
		gzip -dc netbsd.ram.gz > /mnt/netbsd
	7) Compress it and ship it:
		vnconfig -u /dev/vnd0c
		gzip boot.img

That's the process I used. I don't have a machine with a tape drive handy 
to test it (Bruce? Want to try this one?) I tried to figure out if this was 
documented anywhere and I haven't found it yet, but I noticed this was what 
was on the 1.4.1 boot.fs file.
