Miniroot wows:

It took me a long time to get this to go, but this is how I did it:

Apparently the miniroot needs to be on device 0, at lest for me it was so. 

I made an a partition offset at 16 blocks, 

wrote the disklabel with ultrix using the ultrix version of disklabel, 
   disklabel -R -B -b /usr/mdec/bootrz -s /usr/mdec/rzboot /dev/rz0c <prto>

where <prto> is a file containing the disk geometry. 

I then dd seek=16 if=miniroot of=/dev/rrz0c


now a ">boot 3/rz0/netbsd"  worked. 

I now disklabeled the final disk under NetBSD, "a" now should have an offset
of 0, then write the bootblock, mount the disk, and unpack all the goodies.

WARNING: it seems that the old SCSI code is extreamly picky about what disks 
it likes. I thought I was a total idiot when I could not it run correctly, 
but it was the disk, first I tried a Syquest 88 to boot strap, and it did 
noithing, then I tried an DEC rz23, and it booted - but executables failed to
run at random times, then I tried a 600MB micropolis I had lying around - worked better but got random system panics. Finally tried a 5 1/4" 1.0 gig  fujitsu
and all is working reasonable well now.
