If you have a SunOS system available to mount things from, you don't
need to have a copy of even ld.so on your NetBSD box.

Here's what I did.  Mind you, I did it on NetBSD/sparc, but I don't see
any reason it wouldn't work equally well on NetBSD/sun3.

	# mkdir /sun-libs
	# mkdir /sun-libs/usr
	# mkdir /sun-libs/usr/lib
	# ln -s /sunos/usr/nfs/mount/point/lib/*.so* /sun-libs/usr/lib
(note this ln command will make a link for ld.so as well.)
	# mount -t null -o ro,union /sun-libs/usr/lib /usr/lib

That's it.  Then you run your SunOS binary.  (The null mount doesn't
have to be ro; I'm just paranoid.)  Nothing but symlinks and an nfs
mount on the NetBSD machine.

You might even be able to get away with just
	# mount -t union -o -b sunoshost:/usr/lib /usr/lib
though I haven't tried it.

I suspect more likely it was an accident... 8-)
