I am working on a miniroot setup for the Sun3 port.  The first step
is something to partition the disk and install the miniroot in swap.
Instead of using a standalone program for that, I've come up with a
really small ramdisk kernel that can do the job.  The ramdisk setup
can copy the miniroot image from one of several sources:
  boot tape: (mt rewind; mt fsf 1; dd ...)
  NFS mount: (ifconfig ...; mount ...; dd...) *
  remote sh: (ifconfig ...; rsh server 'gzcat mroot.gz' | dd ...) *

I too like the miniroot approach.  Once you have it loaded you can
boot up single-user with a fairly complete set of tools available.

Yeah, that's cool.  I wondered if there might be a way to use FTP
but not have to store the tar images locally.  Would this work?

	# mkfifo /dev/pipe
	# tar xfp /dev/pipe &
	# ftp ...
	ftp> get some_tar_image /dev/pipe

I haven't tried it with FTP yet...
